[MonoDevelop] Monodevelop stopped working: GdkPixbuf-CRITICAL

[Uwe Fechner]

Hello,

today I emerged mono 1.1.4 and the newest version of monodevelop (0.5.1).
It worked fine, until I emerged the new version of glade.

Now monodevelop crashes, if I do anything with it, like looking help pages
or creating a new empty file:

bash-2.05b$ monodevelop

I tried to reemerge all packages, deleted the .config/Monodevelop 
directory, but it didn't help.

Any idea?
