sure thing.  The seg 11 is in glib, so I recompiled it with symbols:

Program received signal SIGSEGV, Segmentation fault.

There are some bad characters in the new_path line above that will not
cut/paste.  There are 5 unprintable blocks before the \177.  It is
passed up as "name" to g_object_new_valist.

This might be an issue with varargs.  On the amd64 and other processors
(i.e. not x86) a va_list gets passed by reference instead of copy.  This
can cause issues if someone expects the arg pointer to be at the
beginning after it is passed to a function that uses it.
