Bug during custom filters

[justinlilly@…]

At the pycon-tech trac ​https://pycon.coderanger.net/ I try to filter by:

new, assigned, reopened priority is not minor, trivial group by milestone

and I get this error (I did it twice to be sure)

Traceback (most recent call last):

Looks like the problem is just that the milestone name has a '.', which makes clearsilver explode. Should we close this as a won't fix since 0.11dev shouldn't be affected?

[Christian Boos]

Well, it's a valid defect for 0.10, so perhaps we should keep it open for 0.10.5 until either someone contributes a patch or we drop maintenance of 0.10-stable.

[Christian Boos]

It seems we'll drop maintenance of 0.10-stable before this will ever get fixed.

Of course, if someone wants to share a fix for this bug, he's more than welcome to provide a (well tested) patch and reopen the ticket.
