Kupfer- no application for XXX (inode/directory)
 

Hi
I just made a fresh debian install. Base system plus lxde. I also installed kupfer but when I try to open any directory with it I get an error:
no application for XXX (inode/directory)

I previously installed pcmanfm and I can open any directory without any problems. What should I do? In kupfer preferences I couldn't find any option to set file manager.
