grr, please disregard previous patches. I've discovered a problem that can lead to use of un-initialized values.

OK, actually it looks like the problem is already in X11DRV_SelectPen and is unlikely to occur, so my patches are good.
Still, I'm thinking that if GetObjectW fails (http://source.winehq.org/source/dlls/winex11.drv/pen.c#L45) then we should immediately exit the function returning zero rather than mucking around any further, setting the pen's ext field to zero, etc. Then PEN_SelectObject (http://source.winehq.org/source/dlls/gdi32/pen.c#L220) wont replace the current pen with the uninitialized data. I realize this perhaps "shouldn't fail" after a successful call to GDI_inc_ref_count, but it still seems more responsible.
