--- Comment #1 from Jason Edmeades us@edmeades.me.uk --- Frédéric - Can you still reproduce this?
I tried - Running the wine tests under wine in a directory with spaces in (all passed) - Downloading a .exe from the testbot and running it - whilst it had 9 failures, that was independent of whether the directory had spaces in or not!
Happy to investigate if you can get me seeing the problem
