Xcode 5.1.1 crash on starting

Question

I've just migrated from Xcode 5.0.2 to 5.1.1 and I'm always getting an exception just when the app is opening and I'm really puzzled with it because I don't know what's happening, I need that version of xcode to test with my device iphone 5s.

This is the exception I'm getting:

Answer 1

Open Xcode's preferences and get rid of all repositories in the Accounts pane.

If that's not sufficient, you may have to take this project out of source control completely.
