[Bug 742884] [NEW] compiz 0.9 crashes unless it runs as root


Public bug reported:

Binary package hint: compiz

When I try to log into the Natty classic desktop (with effects turned
on), it looks very much like compiz is repeatedly crashing. I see the
desktop background for around a second, then some windows (without
decorations) for a second, then the desktop, etc. The keyboard is
unresponsive during this time except that I can get a tty console. This
continues for 10-20 iterations and then X locks up completely (no mouse,
and I can't get a tty console).

If I log in to 'classic desktop with no effects' mode and then run
compiz as root (sudo compiz), it runs fine.

If I run compiz without root privileges, compiz crashes (see attached
crash log).

I can run compiz in another user profile without issues - it only
crashes in my normal user profile, which is shared with Maverick, ie
compiz 0.8.
