I've done some coding in 2.0 this weekend and also seen strange behavior with protocols in Nautilus where all the methods of an object have their protocols shifted by one.
I put methods in protocols A, B and C after a while I see the methods from A in B, from B in C and from C in A.
I suspect it occurs after executing a refactoring but I've got no reproducible scenario yet.
I loaded some morphic games and I have a strange behavior with nautilus.
when I press all I see all the methods but when I look at the protocols I only get a couple
and I do not see all the methods.
