This is a check that indicates you provided the wrong number of arguments to
addMethod, possibly missing a descriptive argument (see Doxygen). Yes, it's
ugly.

2.0 does not suffer from this.

I find these are usually due to missing parameters when adding methods, etc. So something like (written of the top of my head)

methods()->addMethod(&myMethod, "My description")

should actually be

methods()->addMethod(&myMethod, "My description", "param1", "First parameter")
