monodevelop 0.10 fails on startup

[SirErugor]

Hi there..

I recently emerged monodevelop 0.10 but when I start it up I get the following error in the console:

(MonoDevelop:27001): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed

And I get this in a popup-err-screen:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.FormatException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Now I've got these packages installed:
gtk (..gecko, gconf, art, gnomevfs, glade, gnome, gtkhtml, vte..) -sharp-2.8.2 (and 1.0.10)
libgdiplus-1.1.13.2
monodoc-1.1.13
mono-tools-1.1.11
mono-1.1.13.2

I hope someone can help me with this.
Btw. monodevelop 0.9-r1 works like a charm!
