To alecs: Which version do you use?

Latest. If you have menu-cache installed it works. Idea is that menu-cache should be a require for pcmanfm.

Alex, show me output of this command, please:

$ find ~/.config ~/.cache -iname '*.desktop' -o -iname '*.menu'

Created attachment 4879 [details]
find ~/.config ~/.cache -iname '*.desktop' -o -iname '*.menu'

If i click on "applications" and don't have menu-cache installed, it dies.
