Bug in CreateWindowEx

I'm trying to get Civ2 to run under wine (checked out via CVS today),
and I've run into a particular problem. The installation is totally
stand-alone -- all DLLs are built-in.
I get an invalid page fault in X11DRV_GetDC [winpos.c:441], at the line
which says:
drawable = data->client_window
Some debugger work shows that data is NULL. Now, the backtrace shows
that we get *here* from a call to WIN_GetMinMaxInfo from CreateWindowEx
[win.c:885]. The problem, as I see it, is that
USER_Driver.pCreateWindow doesn't get called until [win.c:922] -- in
other words, when the callback inside Civ2 receives the
WM_GETMINMAXINFO, it tries acquiring a DC for some reason, and this
causes the crash.
Now, I don't know enough about how wine works internall to fix this.
Can anyone provide any suggestions?
