udev-discover crashed with ImportError in /usr/lib/python2.7/dist-packages/udevdiscover/devicefinder.py: could not import gobject (could not find _PyGObject_API object)

Same if I try to import the module

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

Running strace -vf udev-discover 2>&1 | grep -i '/usr/lib/python2.7/dist-packages/.*gobject.*\.so' shows that python is looking for the gobject dll in /usr/lib/python2.7/dist-packages/gi/overrides/GObject.x86_64-linux-gnu.so.

So I did this:
sudo ln -s /usr/lib/python2.7/dist-packages/gobject/_gobject.x86_64-linux-gnu.so /usr/lib/python2.7/dist-packages/gi/overrides/GObject.x86_64-linux-gnu.so

Then re-ran udev-discover, which yielded another error:

ImportError: dynamic module does not define init function (initGObject)

Unfortunately, "grep -rl initGObject /usr/lib" yields zero matches.
