Gimp Segfaults on Startup
=========================
Hi,
After spending a whole day downloading, compiling and installing
gimp 1.2.3 and its various dependencies, I was unpleasantly
surprised to find the text "Segmentation Fault" as its only
output. I searched the gimp and gtk lists for "segmentation",
"sigsegv" and other variations, but nothing useful turned up. Let
the debugging begin.
Tried running gimp with various combinations of options, in
particular with any type of shared memory disabled. Conclusion:
the only way to avoid the SIGSEGV is to run with --no-interface.
Secondly, built and ran all examples supplied with GTK; all seem
to work fine. However, the last trace (see below) suggests that
it might be a GTK problem anyway. Since I'm really not sure, I
decided to submit my problem to the gimp list first.
I am very short on time at the moment, and can't be sure when I
will have enough time to dive into the code. I am also completely
new to the GIMP source, and with all due respect, wish to learn
as little as possible about it. Now, before I dive in, does
anyone have any hints, tips, suggestions or pointers to speed up
my quest? Could it even be that this problem is already known?

my gimp and gtk build scripts.))

Hmmm... That looks suspicious. Time to build a debug version.
Multiple nightly rebuilds were necessary to get a debug-enabled
version. Had to free up extra diskspace to make it fit. GRRRR.

Still suspicious, but got the exact instruction where the error
was caught. (Not necessarily very useful.)
Note that libc's internal malloc debugger is enabled during the
above session. (As per MALLOC_CHECK_.)
Let's try a full trace. Third session summary:
==========
(gdb) run

Again, the malloc debugger was enabled during this session.
