No, this is a Gtk# issue. The Gtk.Accel.Map* methods are marked
obsolete and are superseeded by Gtk.AccelMap.*. Note that both
versions point to the same C function.
My line of thinking was that in 3.0 the obsolete methods would be
removed and then there are just 2 methods left in Gtk.Accel. IMHO it's
not worth keeping the class around for two static members and moving
them to e.g. Gtk.AccelGroup would simplify the api.

If I supply patches that add an overload to the current methods, would
marking the current ones obsolete be regarded as a compatibility
break, or is obsoleting OK?
I think this would provide the best upgrade path. Developers could use
the last 2.x release and it would still work, but after changing their
code to remove all the obsolete warnings, the code would run fine on
BTW, I'm on holiday for the next two weeks and will try to provide
patches after that. If anyone wants have a go at making a patch, that
fine too. In any case it would be nice to have some guiding comments
on the bug reports, to steer the patches in the right direction.
