backtrace

Using Firefox 4 (beta 7), all I have to do is point the browser toward bugzilla (so far tried bugs.winehq.org and bugzilla.gnome.org) and Shell dies with signal 11. 

I've attached my backtrace from gdb.

On IRC last night this was tracked down to any unicode code points after 255 appearing in any app's titlebar. So this in fact appears to be a mutter/gdk bug.

not tested yet (need to do a complete jhbuild from scratch to clear up
some linking problems), but I'm pretty sure this is right

looks correct to me.

Compiled fine and definitely fixed here.
