Okay, so you have done everything you could to make sure, and you still
think it's probably a bug. You should then go ahead and file a bug
report. To do this, begin by going to
https://bugzilla.gnome.org/enter_bug.cgi, and go down the page until you
can select the component “GIMP”.
The first time you file a bug report, you will be asked to create a
Bugzilla account. The process is easy and painless, and you probably
won't even get any spam as a result.
This takes you to the bug report form, which you should fill out
as follows. Note that most of the information you enter can be
changed later by the developers if you get it wrong, so try to get
it right but don't be obsessive about it.
Give a one-sentence summary that is descriptive enough so that
somebody searching for similar bugs would find your bug report on
the basis of the words this summary contains.
Steps to reproduce the bug
Follow the directions. Be as specific as you can, and include all
information that you think might possibly be relevant. The classic
totally useless bug report is,
“GIMP crashes. This program sucks”.
There is no hope that the developers can solve a problem if they
can't tell what it is. If at all possible, give a procedure that
will reliably reproduce the buggy behavior, and give it in enough
detail so that a moron could follow it.
Set this to the part of GIMP that the bug
affects. You have to pick something here, but if you aren't
sure, make a guess and don't worry about it.
In most cases you should either leave this as
“Normal” or set it to “Enhancement”,
if it is an enhancement request rather than a
malfunction. The maintainers will adjust the severity if they
think it is warranted.
In most cases you should leave this at “Normal”,
and allow the maintainers to adjust it. Setting the priority to
“Immediate” or “Urgent” usually just
manages to annoy people.
Set this to the version of GIMP that you are
using. Leave the Gnome version unspecified.
Set this to your OS unless you have a very good reason for
thinking that the bug applies to all operating systems.
You can ignore the rest. When you have filled out all of these things,
press the “Commit” button and your bug report will be
submitted. It will
be assigned a number, which you may want to make note of; you will,
however, be emailed any time somebody makes a comment on your bug report
or otherwise alters it, so you will receive reminders in any case. You
can see the current state of your bug report at any time by going to
https://bugzilla.gnome.org and, at the bottom of the page, in the
“Actions:” area, entering the bug number and pressing
the “Find” button.
Sometimes it is very helpful to augment a bug report with a screenshot
or some other type of data. If you need to do this, go to the web page
for your bug report, click on the link
“Create a New Attachment”, and
follow the directions. But please don't do this unless you think the
attachment is really going to be useful–and if you need to attach a
screenshot, don't make it any larger than necessary. Bug reports are
likely to remain on the system for years, so there is no sense in
