I'm not familiar with what you mean by "local GTK", but everything I've 
read recently about Firefox says it uses gnomeui and gnome-vfs if 
available. From that I thought Firefox was more tightly Gnome integrated 
than the other programs I mentioned. Maybe I misunderstood.

Frames 13 through 0 are the same in all the crashes. I've included the 
short gedit backtrace at the end of this email for comparison.

Running gnome-settings-daemon does seem to stop the crash for file 
dialogs, but results in the following error when closing gedit. However 
it does make all the software usable, including Firefox. Jeremy 
suggested I try this earlier but I did not have Gnome installed at the time.

Does any of this help track down the bug, or will it just be a case of 
people needing all of Gnome installed to run Firefox from KDE?
