compiz crashed with SIGSEGV in g_closure_invoke()

[Eric Ongerth]

Brand new installation of 14.10 beta 2. I installed unity-tweak and used it for one thing only: to change fonts. The very first change that I made was to switch the default font to DejaVu Sans 12. Upon doing this, compiz had a crash (recovered, though) and started the automatic report process which brought me here. That's all I know.
