libunity seems to no longer be buildable in wily. This is a problem because it must be rebuilt for Python 3.5, but it is failing for unrelated reasons. Here's an excerpt of the build log from a local build using the current wily source package:

Compilation failed: 12 error(s), 0 warning(s)
Seems like the same problem in all cases, and I'm not sure which ListStore is intended. Full buildlog is available in the Python 3.5-as-default PPA:
https://launchpadlibrarian.net/216183170/buildlog_ubuntu-wily-amd64.libunity_7.1.4%2B14.10.20140808-0ubuntu1_BUILDING.txt.gz
This is blocking several other critical packages which need updating for Python 3.5.
The attached patch gets past the compilation problems, but the test suite still fails:
