Oh my bad, I even forgot to search which package installed
/usr/lib/python2.7/dist-packages/gi/_gi_cairo.i386-linux-gnu_d.so.
It's python-gi-dbg.

Then this bug should be marked as minor and be only about the missing
error message.
python-gi-cairo is only "suggested" by python-gi and the failure to
load the module produce no message whatsoever.

I see the code kinda talks about a TypeError exception. But it looks
like it's never raised.

Or maybe this bug should be maked as invalid and I report another one?
