the tests show failed on tests.winehq.org. When running the tests by
themselves a nice Microsoft Error box is shown (dwwin.exe).

How come the tests have to remain unchanged when crashing? After the first
crash the rest of the tests are not run anymore, hence no tests ! I don't
think we want that either.
