Error with Custom Query when Grouping by Owner

[jason@…]

Running a custom query with the criteria 'Group by Owner' fails if one of the Owner values starts with a period ('.Customer.Followup.Required'). The period on the start is used to ensure that that owner lists first in the reports.

The closest related ticket is #4218, which deals with trailing periods, and not leading periods.

The url of the query is ​http://localhost/trac/query?group=owner&order=priority

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