        Anyone else experience this?  I'm getting constant crashes (every 20 minutes).  Luckily, Xcode remembers my window configuration, but it's getting annoying.  Xcode.sourcecontrol.git is always the culprit, but I get this error code:

         

        0x00000004 (no mapping for user data write)

         

        Thoughts?

         

        The Xcode crash report is here:
