Comment 4 for bug 1067797

Nope, python3-gi isn't ready for python 3.3. No segfault here, just import errors, but I can't fix this from Onboard. Are you able to install python3.2 in parallel to the python package? If yes, you can probably run
$ python3.2 ./setup.py build
$ python3.2 ./onboard
or modify the shebang in setup.py, onboard and onboard-settings to read
#!/usr/bin/python3.2
