Comment 2 for bug 91077

libxcb1 1.0-1.1ubuntu1 .

I'm aware of the patch that went in to stop the notification of these types of problem (Bug #90757 ?). However after Feisty is released this lock checking will be re-enabled so I might as well report the problem in core packages now. I don't object to seeing legit warnings before the final release but was does worry me is the sound blips that this causes as I have been thinking that X has been less responsive than in previous versions of Ubuntu...
