compiz crashed with SIGSEGV in unity::TextureCache::FindTexture()

[Dan Drake]

For some time now, I've been unable to log in to my Raring virtual machine. The lightdm screen comes up (although some icons look wrong) but when I log in, I get a blank screen.

I reported this before, but now have updated debug symbols for tracing.
