cxonsole output with +d3d7,+ddraw debug channels enabled without
directdrawrenderer set

I think both problems are the same (directdrawrenderere and crash when
directdrawrenderer set to opengl)

What happens is a surface is released (its ref==0). Then ddray->ImplType is set
to 0 (Wined3dSurfType=UnknownSurface)
So, Wine complains it needs opengl surface

Moreover this surface is a target surface, but now it is NULL (it was just
released)

 So in the line prev =device->render_targets[render_target_idx];
(file dlls/ddraw/device line 5672)
device->render_targets is null

and then wine crashes because it wants to reach the first element of the array 
device->render_targets, that does not exist.

I m afraid it is probably a refcount issue. Unfortunately these kind of errors
are one of the most difficult to fix :( :(

But maybe I am wrong (I hope :D :D).
