It appears that your /usr/lib/python2.7/dist-packages/gi/_gi.so is missing the g_vfunc_info_invoke symbol/function.
Coud you run this command in a terminal and post the output here? if it outputs nothing, please let us know too. nm -D /usr/lib/python2.7/dist-packages/gi/_gi.so |grep g_vfunc As you mention, /usr/lib/python2.7/dist-packages/gi/_gi.so belongs to python-gobject, and it probably supersedes python-gi, as in my Natty system python-gi is not installed but python-gobject is. So other things to try are: - install the debsums package and use it to verify that the files belonging to python-gobject are not corrupted or missing: sudo apt-get install debsums debsums python-gobject - Reinstall python-gobject to replace any missing/corrupted files (probably only necessary if debsums reports something abnormal, but worth a try anyway): sudo apt-get install --reinstall python-gobject Please let us know if any of this solves your problem, or if the commands suggested here produce errors or other unexpected output, please post it back here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/784622 Title: ubuntuone-control-panel, language-selector, jockey and software- properties fail to start -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
