Hello!
When you do an update of an app which contains optional additional localizations (like Pidgin), the updater will install it full, even if you have chosen "only english" on previous installation.
I would suggest too that there was a option to choose which localizations to be installed, because sometimes is a waste of space install multiple languages that will never use.

I had the same observation, also with Pidgin.

It's dependent on the language of the platform. If the platform is in English, it'll do English only. If the platform is not, it'll do all langs. This will be customizable in an upcoming platform release.
Sometimes, the impossible can become possible, if you're awesome!
