bleachbit.py crashed with TypeError: type 'gio.MemoryOutputStream' is not dynamically allocated but its base type '__main__.GPollableOutputStream' is dynamically allocated

Get that crash on this vivid i386 system booted with systemd-sysv on a gnome-shell session

checking the upgraded packages list recently applied, maybe it could be related to python 2.7.8-3 upgrade

Status changed to 'Confirmed' because the bug affects multiple users.

Probably this:

    - Issue #22079: PyType_Ready() now checks that statically allocated type has
      no dynamically allocated bases.

Looks like many apps are/will be affected by that new function check.
