Trace:

Trac detected an internal error:
TypeError: 'NoneType' object is not iterable
If you think this should work you can reproduce the problem, you should consider reporting this to the Trac team.

Before you do that, though, please first try searching for similar issues, as it is quite likely that this problem has been reported before. For questions about installation and configuration of Trac, please try the mailing list instead of filing a ticket.

Otherwise, please a new ticket at the Trac project site, where you can describe the problem and explain how to reproduce it.

This bug is still here. Its randomish nature puzzles me.
