[Bug 5668] Crash in IDirect3DViewportImpl_SetBackground

[Wine Bugs]

------- Additional Comments From stefandoesinger(a)gmx.at  2006-20-08 16:15 -------
Some suggestions:

-> Can you check if This->ddraw->d3ddevice is != NULL in that function?
-> Add a NULL check for lpDirect3DDevice3 in 
IDirect3DMaterialImpl_GetHandle(material.c)
return DDERR_INVALIDPARAMS if the device is 0 in any case. I suspect that the 
app calls SetBackground without initializing a device before. It passes a 
random material handle because it can't have one without a device.
