I spent ages too tracking down this exact crash, only to discover just
as I worked out what the problem was that Dan had already fixed it:

2005-12-08  Dan Williams  <dcbw redhat com>

        * gconf/gconf.c: (gconf_unescape_string): Don't stomp on
          the function-level scoped 'end' from deep in the function.
          Fixes a segfault.


There aren't any 2.12 releases that have the fix in, but 2.13.5 has the
fix.
