software-center crashed when removing packages with aptitude

[Zygmunt Krynicki]

Binary package hint: software-center

I had software-center opened and pointed at my ppa (ppa:linaro-infrastructure/launch-control-snapshots). I was trying to debug an issue where one of the packages present in the PPA was not listed (python-django-testscenarios). I started aptitude and removed then re-installed that package to check if it would refresh the software-center meta-data.

Instead of refreshing it caused the software center to crash with this python backtrace:
