logilab-astng #101534 pyreverse crash on folder, single files work though [validation pending]

Pyreverse crashes during Parsing of a Jython Project, which can be fully parsed by pylint. The crash appears in different branches, after all files in the directory to be analyzed have been processed ("parsing filename.py..." has been written to the console). If pyreverse is run on every file (including "__init__.py" seperatly it does not crash. Below you will find the traceback. I used the latest versions (as of writing this no older than one hour) of comopon, astang, pylint from the repository, I pulled pylint from http://hg-lab.logilab.org/review/pylint.
