Subject: EGIT branch checkout errors
Message-ID: <491AFB40.4000800@oanda.com>

Using EGIT in Eclipse, I'm able to create a new branch, but not able to 
checkout a branch. When I try Team->Branch...->Checkout, nothing 
happens, so I launched Eclipse from a terminal to see any output it 
might be giving. Here's what I got:
