Ticket report filter exception if multiple empty criteria given

[anonymous]

Add two filters to your criteria which can be combined with "OR" (I was doing it with adding two "Owner" filters). Leave both values emty and click "Update". I get an exception:

TypeError: sequence item 0: expected string, NoneType found

This reproducable on your public site I am writing this ticket on.
