Kdenlive crashes after start

Hello Kdenlive-Users,

I just installed Kdenlive and I wanted to try it out, but it crashes
directly:

see the console-output:
kdenlive: //  INIT EFFECT SEARCH

program

So who knows what goes wrong here? Maybe I missed something during
installation?

Thanks for all hints!
