(some) python based apps wont start with sr_RS locales set

[Slobodan Simić]

Binary package hint: python

Recently I report a bug with software-center wich have problem starting when sr_RS locale are used. Today I installed wicd package and had a very similar error regarding sr_RS locale when starting wicd-client.
So since both apps are python based I think that python is the one responsible for both apps unsuccessful start when sr_RS locale are set. When I change LANG variable before starting these two apps everything works fine.
Here is console output for software-center
