valgrinding mozilla on wine

[Dan Kegel]

I'm trying to track down a wine crash in firefox
(http://bugs.winehq.org/show_bug.cgi?id=4762)
and thought valgrind might be helpful.  So, following
http://wiki.winehq.org/Wine_and_Valgrind
I installed valgrind-3.1.0 and ran

valgrind --trace-children=yes /home/dank/wine/wine
/home/dank/.wine/drive_c/Program\ Files/Mozilla\ Firefox/firefox.exe

This got as far as putting up a window (but not filling it in)
before croaking, so I guess valgrind still has some ways to go.
Before it bailed, it printed out a few interesting warnings:
...
