Code review comment for lp:~seb128/software-properties/handle-no-candidate

One interesting thing to note about the problem instances of the linked error report is that some (at least the first four) have an origin of unknown for software-properties-gtk. I believe this can happen when you install without internet connectivity so there is no information in the apt package cache. However, I tried a fresh install and then manually installed umockdev (and its related packages) to be able to run fake-drivers-wrapper and was unable to recreate the crash.

Its also worth noting that some of the instances are also tagged third-party-packages.
