MonoDevelop 2.8.2 Crash

I installed Unity 4.1.5f1 yesterday which came with MonoDevelop 2.8.2 (on Windows 7). In my Unity project I created a new C# script and double clicked on it to open it. MonoDevelop opened and then immediately crashed with the following error:

System.TypeInitializationException: The type initializer for 'NGit.Util.FS' threw an exception. ---> System.ArgumentException: Illegal characters in path.

I get this error every time I try to open a script, so I’m basically stuck. I’ve searched for an answer to this, but the only suggestions I could find were from last year from people using Unity 3.5, and the consensus was to reinstall Unity/Mono. This is a fresh install of both on two separate computers, and the same thing is happening on both machines.

I get the same issue: MonoDevelop v2.8.2 crashes after a few seconds every time I open it on Windows 7. Fresh install of Unity 4.2.2f1.
