Crash while doing a login/logout in the Timeline

[Christian Boos]

This is somehow reproductible, though I got slightly different stack traces each time. But it always bombs in connection_commit, though.

Configuration:

• tracd on Linux
• python 2.3.4
• pysqlite 2.0.4 with sqlite 3.2.7.

With older versions of pysqlite, I got simply dead-locks, but this was not a good thing either…

Here's the stack trace:
