Problem with playlist using upnp-server

[be.bam]

I am running a mediatomb upnp-server in my network and when I am trying to add a certain track or folder to my playlist it is added 11 times. It's the same for vlc 2.0.0 and vlc 2.0.1 using linux and windows, preferences have already been resetted.
Is anybody out there experiencing the same problem or has an idea where to find a solution?
Thanks in advance

/edit
This is the output of the debugger for "rightclick -> Add to Playlist"

Same problem for me with VLC 2.0.1 in Mageia Linux.
