'winetricks wmp10' works around.

>From what I've gathered through debugging it seems the NULL pointer access is
related to IWMPControls::stop().

The pointer accessed could be IWMPControls* returned by
IWMPCore::get_controls().
Unfortunately I didn't find any FIXME reference to IWMPCore::get_controls() in
trace log (stub right now).

It's probably triggered by some code not in place yet because WMP is
work-in-progress and various parts are incomplete.
