  err:wgl:is_extension_supported No OpenGL extensions found, check if your
OpenGL setup is correct!

This happens because in dlls/opengl32/wgl.c wine_glGetString takes this path

  /* this is for buggy nvidia driver, crashing if called from a different
     thread with no context */
  if(wglGetCurrentContext() == NULL)
    return NULL;

The check has been there since mid 2008
(d6a6b88f1904783157245cae0b3f5a8d3de1ec20).  I don't know much about how all
this works but it does crash without the check.  I wonder (with my uneducated
guessing) if it would be better for Wine to try harder to work around the
"buggy nvidia driver" behavior rather than simply failing.
