This is really strange. There seems to be a project with location null in your workspace:

45	String projectFilePath = p.getLocation()
46		.append(".project").toOSString(); //$NON-NLS-1$

Can you check the projects in your workspace? Execute "Properties" on the project node and check the location.

I have the same problem with any version of Eclipse or Egit. As long as I have I have a Remote Project in the same workspace, I get the same error as the reporter of this bug.
The remote projects have the following pattern in Properties - Location: "rse://xxx.xxxx.COM/home/vlad"

I get the same error (see below) if I have any projects that are closed in my workspace. Opening the projects back up solves the problem. At least until I close a project again.
