--- Comment #24 from Vladimír Čunát <vcunat at gmail.com> ---
I updated glib to 2.36.1 + I disabled SANE_MALLOC_PROTOS (see
https://bugzilla.gnome.org/show_bug.cgi?id=698716), and the crashes seem to
have disappeared for me (one day of using now).

I also have a coredump of one of the previous crashes. If you're interested, I
could post the binaries with symbols inside and the core somewhere so you can
inspect yourselves. I looked at the disassembly just before the crash: it's
somewhere inside g_slice_alloc (it's -O2 so the calls above probably got
inlined) and there is a series of pointer dereferences (some a bit ofsetted)
with 0-tests, so essentially walking some 0-ended linked list, until it gets
into a place where there's 0xffffffff00000000 and at dereferencing this it
SIGSEGVs.
