If you're in object review and your navigator object is on an object with no location (obj.location is None), switching to screen review throws this error:

ERROR - scriptHandler.executeScript (22:09:53):
error executing script: <bound method GlobalCommands.script_reviewMode_next of <globalCommands.GlobalCommands object at 0x05631BB0>> with gesture u'NVDA+numpad 7'

RuntimeError

This is not a regression; it occurs when switching to flat review with 2013.1 as well.
Blocking #3517

In [269c7be]:

displayModel.DisplayModelTextInfo._getOffsetsFromNVDAObject: raise LookupError instead of RuntimeError when an object has no location. Allows switching to screen review when the navigator object has no screen location. Fixes #3454
