Bugzilla search fails with TypeError: Parser must be a string or character stream, not datetime

[Mossop]

Using the latest master from this repository I'm trying to create tasks from a custom search on Mozilla's bugzilla for bugs that have a flag set on me. This is what I'm getting. A similar search for bugs that are assigned to me is working fine.

Traceback (most recent call last):
