Unfortunately the backtrace is rather useless. I do have the matching libc6-dbg, it just doesn't seem to help here.
I have used eglibc 2.15~pre6-0ubuntu4 from https:/ /launchpad. net/~ubuntu- toolchain- r/+archive/ glibc/+ packages since last week. Yesterday I noticed that this causes a crash in the gdk-pixbuf loader cache when it tries to examine the SVG one.
This can be reduced to this test case:
With precise's libc6 2.13, it works:

With the PPA version it crashes:
