Comment 11 for bug 905686

We're in the process of updating the X stack in Precise (post-alpha-2), including a new libxcb and other bits. There have been several fixes for threading problems, and are wondering if they'll (finally) resolve this long standing problem.

If you are able to reliably reproduce this bug, then after these changes land (within the next day or two) please re-test and report back if it still occurs. If you do still see it, please include your libxcb version and the stack trace you got.
