    When I try to open MonoDevelop from Unity, I get two errors thrown

    First:
    System.NullReferenceException: Object reference not set to an instance of an object.
    at MonoDevelop.Ide.Gui.Components.ExtensibleTreeView.GetBuilderChain(Type type) in c:\buildslave\monodevelop\build\monodevelop\main\src\core\MonoDevelop.Ide\MonoDevelop.Ide.Gui.Components\ExtensibleTreeView.cs:line 1364

    at GLib.Timeout.TimeoutProxy.Handler() in c:\MinGW\msys\1.0\home\builder\gtk-sharp\glib\Timeout.cs:line 70​

    Second:
    System.NullReferenceException: Object reference not set to an instance of an object.

    at Gtk.Application.InvokeCB.Invoke()
    at GLib.Timeout.TimeoutProxy.Handler() in c:\MinGW\msys\1.0\home\builder\gtk-sharp\glib\Timeout.cs:line 70​

    Is this a problem that I can fix or do I just have to wait for a patch to Unity? (I think I've auto-reported these errors quite a few times now trying to figure out if it was user error.)
