TypeError: unhashable type: 'list'

[lukasz.matecki@…]

While on the following page: ​http://trac.edgewall.org/wiki/TracDev/ReleaseNotes/1.0#MaintenanceRelease

I've clicked the 1.0.1 progress bar (the last one) and got this.

How to Reproduce

While doing a GET operation on /query, Trac issued an internal error.

Thanks!

The corresponding TicketQuery is:

[[TicketQuery(milestone=1.0.1,group=milestone,format=progress)]]

Funnily, it's only happening for the "closed" ones.

Ah, looking in the "About" page, I see this:

milestone-groups	closed.query_args	group=resolution,order=time,col=id,col=summary,col=owner,col=type,col=priority,col=component,col=severity,col=time,col=changetime

So here's where the 'time' comes from, in 'order': [u'time', u'id'].

Duplicate of #10838?

Ah right! It would be good if you could assign that one to yourself, as you already provided a patch. That way, one can identify the "work in progress" more easily as the ticket ends in the yellow group of its milestone.
