<coderanger_> jg: The problem is we cache the results of the current query for speed, and that list now contains deleted tickets for you.

Oops…
Trac detected an internal error:

TypeError: can't compare datetime.datetime to int

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 ==== How to Reproduce ==== While doing a GET operation on `/query`, Trac issued an internal error.

The problem is if a ticket in the cached query list doesn't exist, its time is 0, not a null datetime object.
