What the summary says. Pcmanfm appends the directory name to the path a second time.
e.g. if I go into /root/.config and run a search for '4', then click on the search result, I get this error message:
The specified directory '/root/.config/libreoffice/4/4' is not valid
Of course it isn't valid - that directory doesn't exist, only this one does: /root/.config/libreoffice/4
FWIW I'm using current git on Arch Linux.
