I saw this just now.

If visiting a link from firefox causes the crash it's an interaction from
firefox.

I suspect a panel plugin triggering this. Maybe the one listing window titles
is being confused by the title of the page. It's quite probable the problem
shows up only if using a specific locale.

The fonts you're using can be missing some language specific glyph, for
example.

If I'm right this is not easy to reproduce for someone using a different locale
and font set.

Unluckily the gdb output you posted is not very useful, missing the whole
backtrace.

Before grabbing and posting the gdb output you should give it the "bt" command
and grabbing the output of that too.

Obviously gdb output can be made much more useful by having debug symbols in
binaries, but it's not always strictly needed.
