It is next to impossible to tell what is going wrong here. I'm afraid someone will have to dig into the GL calls and try to reproduce the crash in a stand-alone app and report it to Nvidia. That can be a quite nasty task. You might be able to get your app running by disabling d3d9.dll(d3d9="" in winecfg).
WineD3D works pretty well with Nvidia cards in general. It's the non-nvidia drivers that make most troubles, the open source ones and to a smaller amount the ATI binary driver(getting better and better each release).
