I think this problem triggered for me. I have
[28182.855672] gnome-shell[1909]: segfault at 1 ip 00007fba077bed12 sp 00007ffd6eac3df0 error 4 in libgobject-2.0.so.0.5600.1[7fba07789000+52000]
I didn't install all dbgsym packages that find-dbgsym-packages suggested
because my system is somewhere between sarge and unstable and I would
need to pick the right dbgsym packages from snapshot.d.o. So I only
installed the stuff that I considered important (or easy). Tell me if I
missed a critical package, I conserved the corefile. For a quick word I
also idle as ukleinek in #debian-gnome, just hilight me.
