It looks like you have used the very very first 0.11 version... To me it looks like http://egit.eclipse.org/r/#change,2419 should fix this. Could you please try again with a current 0.11 (at the time of writing, this would be 0.11.0.201102071227)?
I'm currently building my own based on master, but I will try from 0.11 and let you know.
Works fine when building from 0.11.
So can we close this?
Yes. I didn't close it since I don't know if there is a bug tracking the original change or it should be just set to fixed.
Fix was merged into 0.11 stable as 6bfa7be26b140e222f8846c8ff561241c7c9caa9 It will be merged back into master once 0.11 is out.
