If the gem has in memory a method breakpoint in an unbound method, Jadeite breakpoint browsers and debuggers will fail with an MNU in RowanQueryService >> methodServicesFrom:.
To reproduce, execute in Jadeite

| method |

method :=
     '' _compileInContext: nil
          symbolList: GsCurrentSession currentSession symbolList.

method setBreakAtStepPoint: 1.

^ method

then open a debugger or breakpoint browser. The resulting stack is below. The cause appears to be that the breakpoint is in a method whose class is nil, and nil is being sent #thisClass.

To see this failure the server must be recent enough 3.7 to have the fix for bug 49650, which caused an earlier MNU but was fixed a month ago.

A very similar issue in GBS was reported as bug 49682, and subsequently fixed to list the class as "nil."
