I tried now with a cvs snapshot of gtk-sharp and monodoc, it does compile,
but it doesn't run. I didn't update mono and mcs though, because I couldn't
get the snapshots of these to compile. I'll take a further look at that later.
My time is too limited, almost have to go to sleep again :-)

The error I'm now getting when I start monodoc is different, so I post it,
perhaps this error gives better clues :

Spanish course and perhaps I even got this wrong :-) )
