Francesco and me looked at it few weeks ago. There is a global udev context
in one of the library we use, and this context __del__ is called
during shutdown,
which never works since python is halfly destructed at this point.

I think the issue was in blivet. The solution for this is to replace
the automatic
initialization on import and destruction on system shutdown by
explicit life cycle
in the library.

This can be also solved in udev by writing proper C extension instead of using
ctypes.
