Comment 1 for bug 724815

This happens because dbusmenu implements an interface that is in a package unknown to giraffe. The planned solution is to add a command line switch to giraffe --external=filename.gir that can be specified N times. The external girs will be used to resolve interfaces and class inheritance, but will not be included in the generated docs.

As an intermediate solution everything should work if you add the Atk.gir to command line args when generating the dbusmenu docs.
