I had a look at a +shdocvw trace and looks like this is the problem:
warn:shdocvw:ClientSite_QueryInterface Unsupported interface
{9c2cad80-3424-11cf-b670-00aa004cd6d8}

the uuid belongs to interface IOleInPlaceSiteEx

I think that's the problem as the hack below makes the main gui start up fine
for me. The window remains still black, that can be "solved" by using native
oleaut32. Let's see how difficult it is to create some kind of acceptable
patch....
