Comment 3 for bug 1024204

Well, something very related (for a novice, at least) occurred to me in: Bug #1244198
so it seems some regression might be out there.

My output when upgrading from 13.04 to 13.10...
Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install. Trying to recover:
Setting up python3 (3.3.2-14ubuntu1) ...
running python rtupdate hooks for python3.3...

and dpkg --contents (= dpkg-deb --contents) to list their contents.

dpkg: error processing python3 (--configure):
 subprocess installed post-installation script returned error exit status 4
dpkg: dependency problems prevent configuration of foomatic-db-compressed-ppds:
 foomatic-db-compressed-ppds depends on python3; however:
  Package python3 is not configured yet.

So, I'm stuck for the moment with a non-functional system.
