Title: Fixing giant log files/memory leaks

WMException was printing traceback.format_exc(), which spits out all the
information for an exception. In the case of nested exceptions, this
would cause the size of the error message would grow geometrically.
Also, WMException was looking for member variables it didn't have, so it
would end up failing in __init__ (classy)

kudos to @dballesteros7 for finding that one and making it reproducible
