Well, that shows that *something* is working.

X problem.  Somewhere in the lower levels of whatever this is doing,
it made a bad GTK+ or GDK call.  (Or if you're really unlucky, one
of those libraries is doing something stupid.)  Getting info on
this with strace will be difficult as X calls are typically made
over... yep, a socket.  Like the error says, you'd probably have
to compile with -g, run with --sync in gdb, and break on the
function mentioned.  Not the world's most fun thing to do.

That'd be the easiest thing to try, see if they have another
point release....
