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 http://bugzilla.gnome.org/enter_bug.cgi, and go down the page until you can select the component "GIMP".

	Note
	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.

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 http://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 wasting memory.
