[Daniel van Vugt (vanvugt)]

This is odd. It's in a thread and compiz does not explicitly create threads. Also, there is no compiz code in the stack trace. But it is the compiz process.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

This bug is incomplete because we don't have enough details to work with. Only if someone can figure out a reliable test case will this change.
