Git project is not recognized by xcode

I have a project that usually works with Xcode 4, however since upgrading to Lion and Xcode 4.1 it doesn't seem that I can commit my changes anymore. I have git setup in my project folder. I've tried to commit using terminal, but in xcode I only have the "Unable to load revisions" message.

In File -> source control, many things are grayed out as well.

Does anyone know how to fix this?

Just to help, I've tried:

commiting form terminal
making sure git installed in /usr/local/git
clean install
remove project from organizer and add it back again

Solution

I'm not sure what I did, but after restarting my computer it seems to be working again... So if you guys are having some problems try to restart your computer first :)
