[Kde-bindings] QTreeView with Qyoto and Kimono

[Tim Taubert]

Hey,

I'm currently trying to develop a text editor with Mono/Qyoto/Kimono. I 
have a problem with the QTreeView component that uses a custom Model 
(same error occurs using QDirModel). Every time I try to expand a 2nd 
level node the application crashes with the following error message:

*** glibc detected *** /usr/bin/mono: malloc(): memory corruption:

Any ideas? Need some more information? :)
