[Bug 629757] [NEW] compiz runs fallback window manager after unlocking screensaver

 

Public bug reported:

Binary package hint: compiz

Steps to reproduce: 
1) wait for screensaver running (any, even "black screen" will do)
2) try to unlock screen by entering password

What is expected to happen: screen unlocks, I'm continuing to work
What happens: *sometimes* compiz runs metacity saying in console something like "starting fallback window manager"

There's no hints on segfault (even running `compiz --debug`, no hints on
console and in logs as well), it just starts metacity after unlocking
screen. Sometimes. Or just works. Sometimes.

1) Description:	Ubuntu 10.04.1 LTS
Release:	10.04
2) compiz:
