If you find a bug or think you find a bug, it is very important to report it. If the developers don’t know it is broken (or might be broken), they can’t fix it. So there you are at your computer trying to do something with GIMP and it freaks out at you. It can be a frightening experience at times.
First: Get out a piece of paper or open a text file and scribble down everything you can remember about what you were doing when it happened. Also write down the exact wording of any error messages you received.
Next: Go away and yell and scream and do whatever you need to do to relax again.
Third: Check to see if your bug has been reported yet. Go to the Current Issue List to see if something that looks like your bug has been reported yet. Don’t worry if it has, you can still help. See the section: Enhancing Bug Reports. If you can’t find something that sounds like your bug there, you will need to report it.
The goal of the following is to give the developers as much information about what goes wrong as possible. This helps them find out what needs to be fixed.
gimp --version or the about dialog (
Help → About GIMP) to check your GIMP version. Next check with www.gimp.org to see what the most recent GIMP release is. If your GIMP is old, update then try to to reproduce the bug. Your bug may have been fixed in the most recent release. If you are running GIMP from Git, update and and recompile.
Attempt to reproduce the problem. Go do what you were doing when it happened and see if you can do it again.
If using GIMP for GNU/Linux, start the program from a terminal with the command
gimp. Sometimes the program will output error messages that can help. This is especially important if GIMP crashes completely without warning. After reproducing the bug, copy the error messages from your terminal into somewhere where you can save them for the bug report. It is better to give too much information than not enough.
To narrow down the exact cause of the problem, attempt to reproduce it in other ways. Prepare yourself to explain how to reproduce it in your bug report. If you are running GIMP in another language, try switching your GIMP to English so you can report menu items exactly with the English menu item name. It helps - developers generally understand English). If you cannot reproduce the bug, assume it was some weird freak event and don’t report it. If it recurs, consult with your appropriate user mailing list. Perhaps someone else can find the key to reproducing it.
Go to GIMP issues. If you don’t have a login yet, follow the directions to create one. The reason to do this and report a bug with your e-mail address is so the developers can contact you if they have any questions. That way if we miss some useful tidbit of debugging information, they can tell you what to do to get it. Log in.
Select “New issue”.
Choose a template to pre-populate the Description field with important information to help the developers track down the problem:
Give your bug a good Title and if you chose a template you should see some text in the Description field already.
Here in the Description you’ll have to tell the developers everything about your system, your version of GIMP, and your bug. Just do your best to tell them about it. A crappy bug report is better than no report at all, but if you write down everything clearly you’ll be going a long way to helping get the bug addressed.
Remember, try to be as clear and concise as possible! This is immensely helpful in tracking down what the problem is and how to possibly fix it.
Finally, please add the output you get from running
gimp --version --verbose to your bug report.
If someone has already reported a bug like yours, read the bug report carefully. Read through all the additional comments. Make sure every bit of information you know about the bug is in there. If your version is different or you had a slightly different experience with the bug, add a comment providing your information. Check the status of the bug carefully. If it is marked “NEEDINFO”, see if you can provide the information needed. Do not add a “me too” comment unless your comment provides additional information that might be helpful for the developer.
If you have provided a bug report and later get more information (like a more specific error message or fancy stuff like a trace), add a comment to your original bug with that information. It is especially important to add a comment if you somehow resolve your bug. For example, you update something else on your system and the bug no longer appears. In that case, add a comment describing what you updated from what version to what version that resolved the bug.
Whee!! You survived! If you managed to get through all this and submit your bug report, be happy. Be proud. You will later get e-mails about your bug. It might include a request for more information. If you get something that says your bug is not a bug, do not be discouraged from reporting in the future. Next time it might be. Submitting careful bug reports and providing additional information where possible helps make GIMP better. The day will come where you submit a bug and later get an e-mail that says your bug is “FIXED” or “RESOLVED”. Then you will know that some developer out there found your bug, reproduced it, and fixed it.
