Okay, thanks.
To illustrate the problem I created a new minimal Glade# project using
MonoDevelop and edited the gui.glade file with Glade. I added a MenuBar,
removed all the stock items that's in it by default and added one
non-stock item to it. It compiles but I get the error messages I
mentioned previously.

Some version numbers:
mono - 0.91
gtk-sharp - 0.91

I've attached the source code file, the glade file and the error
Sorry for not getting your hint about providing more information -
English isn't my native language you know :)
