[MonoDevelop] monodoc problem

[A.M. Abdelaziz]

I have mono, gtk-sharp-2.12 and mono-tools from svn at revision 148843
(latest, just checked now)
when I start monodoc (using any engine Gecko,WebKit,etc) I get the following
message after opening a page or doing something like that:

*** (browser:1608): WARNING **: Missing method
System.Type::op_Equality(Type,Type) in assembly

handle the exception.

what does it mean that the core lib misses the method
System.Type::op_Equality ?
NOTE: this method appeared *after I upgraded mono (the old version was only
older by a weak* or so), I then upgraded monodoc and gtk-sharp-2.12 hoping
that will solve the problem but it didn't


I hope I've provided all imp. information
thanks in advance
