[MonoDevelop] Random crashes still happen in MonoDevelop 1.0

Hi guys,
    I encountered the same thing even more serious, THAT it never works - from I compiled the source.

    My configuration:
        Fedora 8, x86_64, chinese
        gcc 4.1.2
        mono 1.9.1
        gtk-sharp 2.12.0
        monodevelop 1.0
        AMD X2 3800+, 64bit

when i start monodevelop, it always throw exceptions like this:

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

  at (wrapper unknown) Gdk.Rectangle:PtrToStructure (intptr,object)

  at (wrapper managed-to-native) System.Runtime.InteropServices.Marshal:PtrToStructure (intptr,System.Type)

  at Gdk.EventExpose.get_Area () [0x00000] 

  at MonoDevelop.Components.DockToolbars.DockGrip.OnExposeEvent (Gdk.EventExpose args) [0x00000] 

  at Gtk.Widget.exposeevent_cb (IntPtr widget, IntPtr evnt) [0x00000] 

and I got a snapshot of it:

there may be something wrong in my installation, but many other Windows.Forms based applications work well, one dialog of that shown as below:

they rarely throw an exception, and none for my application migrated from windows (created by Microsoft VC# express).

so, I think the problems are from monodevelop itself. It interacts with gtk through gtk-sharp and often throws unexpected exceptions. I have checked the source code and no effective informations been found. 

 monodevelop need full-functional test, especially the graphics part. and I would be happy to do that if md-group wanted.

  I still experience random crashes while working with Stetic in MonoDevelop 1.0. This bug used to exist in previous versions, too. I tried recent gtk-sharp versions like 2.8.5, 2.10.4 and 2.12.0 and these crashes still happen. My OS is Ubuntu 7.10. I installed all of the available updates.

  It happens mostly while working with buttons. I created a simple window with an HBox and 3 buttons and changed some of their properties, associated some event handlers to them. After doing this for about 3-4 minutes, MonoDevelop crashed with the debug stuffs I have attached to this message.

  Is there any solution to this issue?
