That looks to me like a version mismatch: I'd guess at some point
g_callable_info_skip_return got added or removed and you've got files
from either side of that change. 

The first thing I'd do is have a look in
/usr/lib/python2.7/dist-packages/gi/ and see if there are any other
files starting _gi. in case there's two versions there and the import is
finding the wrong one. 

I that doesn't turn up anything then I'd go with removing and
reinstalling the package providing this. First find out which package it
is: "dpkg -S /usr/lib/python2.7/dist-packages/gi/_gi.so". Then use
apt-get to remove it (and check that
/usr/lib/python2.7/dist-packages/gi/ is gone) and then reinstall it. I
suspect it'll be a package that ubuntu-desktop depends on: if you have
to remove it (and possibly others) as well take note of what's being
removed and remember to put it/them back too.
