E.g., gdiplus, which normally is valgrind clean, shows:

  Uninitialised value was created by a stack allocation
    at  SetBitmapBits (bitmap.c:449)

That machine is having some hardware issues, so a regression test will be
delayed. Huw, if you can't reproduce, let me know and I'll try it elsewhere..
