Bug ID: 53819
           Summary: some versions of Unity engine need GetWindowTheme
                    implemented to properly display crash dialog
           Product: Wine
           Version: 7.18
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: uxtheme
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

So, I've stumbled upon a Unity engine game that crashes every now and then due
to what seems to be virtual mapping space exhaustion. Not sure about the crash
itself - it's more likely to be graphics related that winegstreamer, but that's
just a guess.

Anyway, once the crash happens, console is flooded by:

03b0:err:module:DelayLoadFailureHook failed to delay load
uxtheme.dll.GetWindowTheme
wine: Call from 7B0123C6 to unimplemented function uxtheme.dll.GetWindowTheme,
aborting
03b0:err:seh:KiUserCallbackDispatcher ignoring exception

and the Unity crash dialog doesn't display properly.
