Fix for 500 is in ps/1545. It's still interesting why SVN returns None as date for some entries. That's worth looking into, because current showing "unknown" is this case may be not ideal.
Fix for 500 merged to dev, keeping open hoping to look into SVN's date=None issue.
I'll make a new ticket for the SVN date is None issue.
