Thanks for reporting this issue.

Are you able to reproduce it with the final version of Ubuntu 10.10?

I have already moved on to natty with the computer that experienced
these problems under maverick (developement branch). However, even
before upgrading to the new development release, I have not had this
issue for a while.

OK, thanks for your comment. I'm pretty sure we got this fixed before Maverick released, so I'll close the bug for now.
