"pydoc -k ." hangs

[Daniel Hahler]

I have noticed that "pydoc -k ." hangs on my system.

This method is used by vim-ref (https://github.com/thinca/vim-ref/) to get a list of all entries.

Stepping thorugh it via "ipdb", it hangs at:

> /usr/lib/python2.7/dist-packages/gi/module.py(171)__getattr__()
    170 elif isinstance(info, RegisteredTypeInfo):
--> 171 g_type = info.get_g_type()
    172

Upgrading python-gi to 3.11.5-0ubuntu1 (Trusty) (from 3.10.0-1ubuntu1) fixed this particular issue. Now `pydoc -k .` segfaults instead (later on).

With `strace -f`, this is where it hangs:
