MonoDevelop crash for OutOfMemoryException

I had intalled Unity 4.1.1 on Windows 7.
From when I installed it MonoDevelop have began to crash without doing anything.
After few minutes it's opened, even without modifing anything both in the editor and from inside Mono itself it crashes giving the following message:

I thought was a bug with Unity 4.1.1 release, so I unistalled it and rollback to 4.1.0 but now it still crashes with the same message.
I'm not doing anything (I tried also with an empty new project). I open Mono and after waiting a variable amount of times (1/2 minutes) it crashes.

Any idea?

 

I've monitored resouces . When opened MonoDevelop increasingly consumes all of my RAM memory. It had never did that before. Any idea?

 

The 4.1.1 version leaved some undefined dirty references inside AppData directory. After removing them relatives AppData files MonoDevelop began to work again. I'm not sure what was the problem, but if anyone out there has still problems relative to 4.1.1 release, consider removing the Unity folder under AppData.
