Turns out I am able to reproduce this, I just misunderstood the symptoms
because something is trapping the segfault when not running under gdb and
idesk was therefore exiting silently instead of throwing an error message.
And I've tracked the problem down to some amd64 assembly code in
libImlib2.so.1:
#0 0x00002b9b2be201ff in __imlib_amd64_blend_rgba_to_rgb_cmod ()
from /usr/lib/libImlib2.so.1
#1 0x00002b9b2bde8d14 in imlib_blend_image_onto_image (source_image=0x553800,
merge_alpha=1 '\001', source_x=0, source_y=0, source_width=5593504,
source_height=48, destination_x=0, destination_y=0,
destination_width=48,
destination_height=48) at api.c:2015
[...]
The instruction at 0x00002b9b2be201ff is:
0x00002b08934011ff <__imlib_amd64_blend_rgba_to_rgb_cmod+47>: movdqa
1155461(%rip),%xmm5 # 0x2b089351b38c <c1>
I have no idea what this does, other than that it segfaults. The easiest
fix I see is to simply disable the amd64 assembly in libimlib2 until someone
can take a look at and fix it; this can be done by adding a --disable-amd64
option to the configure command in debian/rules. I've confirmed that doing
so fixes the segfault on my test system.
Cheers,
