New XCode 4.6.1 Corrupts Provisioning Profiles

I have noticed several crashes when managing several profiles on xcode and ten updating to 4.6.1 turns out its a known issue...

The Apple way of solving this is to delete the database from xcode; i got this from the forums...
(From Terminal type the following 2 commands)

mkdir ~/Library/Developer/Xcode/OldPortalDBs 

mv ~/Library/Developer/Xcode/connect1.apple.com* ~/Library/Developer/Xcode/OldPortalDBs
