Hello all,First up, I hope that this is the right place to report this bug. Second thing: This is a great product. You guys should be proud of yourselves!
Now the bug report:
Here are the steps that I follow to reliably crash GIMP:
1. open a 1600x1200 image
2. resize image to 132x99
3. right mouse button -> file -> save as
4. rename file, but leave as a JPEG
5. Select the quality slider with the mouse
6. hold down the keyboard left or right arrows (left goes further :-)
7. Go back to console and press 'E' to exit the crashed gimp...
I have no reason to believe that steps 1-2 make sweet rafoosle difference. I suspect, but of course cannot verify :-) that this is a threading issue, since if in step 6) if I press the key one step at a time then the problem does not occur. Also, if I make the image "large enough" the problem does not occur. Maybe the preview engine stomps on something while it is being read by the main window? My guess is that "large enough" is anything that takes long enough to encode that the drawer is definitely finished with it by the time the new image is overwritten. I am guessing this based on the Gtk error messages, but have never looked at the code, so should probably let you folks do that :-)
I am not on the dev list for this project, so if you want more information, or would like me to test a source patch (yes I have the power of the source...) then please contact me directly.

Now all the guff.
I am using the helix distribution levered onto SuSE 7.0.
Here are what I suspect are the relevant packages:
gtk-1.2.8-32_helix_1
libgimp-1.1.26-0_helix_1
gtk-engines-0.10-0_helix_2
gimpperl-1.1.26-0_helix_1
libgimpd-1.1.26-0_helix_1
gtkdev-1.2.8-32_helix_1
gimp-1.1.26-0_helix_1
Here is the stacktrace:
machine$ gimp p9030083.jpg
Gtk-WARNING **: invalid cast from `(unknown)' to `GimpDrawable'
