I think the problem is that Glade uses the indices of the items in the
GnomeUIInfo struct, so since you added the GNOMEUIINFO_HELP item it messed
the generated code up.

In Glade 0.5.9 there is a project option to support Gnome Help, which adds
this macro, so you could use that.
Otherwise you could try updating the indices.

Or run it in gdb with --g-fatal-warnings and you'll see where the first
problem is.
