Comment #3 on issue 591 by pekka.klarck: Inheriting ExecutionFailed exception without calling ExecutionFailed.__init__ crashes test execution with RF 2.5
http://code.google.com/p/robotframework/issues/detail?id=591
I just checked that `timeouted` attribute was added to `ExecutionFailed` in RF 2.1.3. The provided example wouldn't probably work in that version either.
