[Bug 843002] Re: Crashes when "For Purchase" apps have been installed

[Rodney Dawes]

It seems like if python-apt is going to support users not being able to
read certain files, it should handle them gracefully instead of raising
an error and not letting the apt.Cache API be usable at all.

I'll work around this by adding a fallback in ubuntuone-installer, but
I'm also adding python-apt to this task, as it needs to handle this
gracefully.
