For some reason I didn't look at this until now. The contents are:

These segfaults at least don't seem so random. Every single one is in
the same code in libglib-2.0.so.0.5800.3. (The ip addresses differ due
to ASLR, but the offsets are the same.) The code bytes correspond to
part of the g_slice_alloc() function.
That seems more likely to be a bug in libglib, or perhaps some
intermediate library.
