gnome-app-install crashed with ValueError in _refilter()

[Alexej]

Binary package hint: gnome-app-install

In Add/Remove applications I switched the "show"-filter to show all apps supported by Canonical, and chosen "All categories"
After that i switched the software category to "Office" and "show"-filter to "all available application". The Error message appeared.
