exception when refactoring renamig

[Nicolò Chieffo]

Binary package hint: monodevelop

whenever I try to (refactoring) rename something in my class, monodevelop throws an exception (but the renaming happens):
System.NullReferenceException: Object reference not set to an instance of an object
  at MonoDevelop.Core.Gui.ResourceService.GetIcon (System.String name, IconSize size) [0x00000]
  at MonoDevelop.Core.Gui.ResourceService.GetBitmap (System.String name, IconSize size) [0x00000]
  at MonoDevelop.Ide.Gui.BackgroundProgressMonitor+<BackgroundProgressMonitor>c__AnonStorey40.<>m__38 (System.Object , System.EventArgs ) [0x00000]
  at Gtk.Application+InvokeCB.Invoke () [0x00000]
  at GLib.Timeout+TimeoutProxy.Handler () [0x00000]

steps to reproduce:
- create a new C# console solution
- right click on the class name "MainClass"
- choose "Class MainClass" "Rename"
- give a different name and click ok

Same hier on Karmic. Trying to refactor class names, variable names etc will throw an exception and eventually don't rename anything (variables are not renamed).

This bug is chronic. Making my life miserable. Please fix soon or at least put a workaround. Oh and I know I can manually rename them but I'm having trouble in the context of a gtk.window with an auto generated partial classes for the gui design. Any suggestions?

The_steiny:
Just update to MonoDevelop 2.2.
It's much better :)
