Ticket Query grouped by owner causes error

[Max]

Started at ​http://dev.DOMAIN.com/trac/site/query?status=new&status=assigned&status=reopened&group=owner) Opened the only 'Owner: None' ticket and closed it, resolution invalid. Hit back arrow twice to return to the initial ticket list and got the following stack trace:

Yeah, got that as well a few weeks ago, when testing. I could see then that it was a 0.10.x specific issue (i.e. it was not a problem on trunk anymore).

This is a duplicate of #4218. It has been fixed for the upcoming 0.10.4 release.

It is upcoming in 2010 :)

Well, there are no further changes planned for 0.10.4, and if you can't wait, it's fairly easy to get it straight from the svn repository: see TracDownload#Tracstable.
