Greetings, Capricorny.
AFAICT, PCMan needs fuse to do something with policykit in creating LXDE,
so gvfs comes in with PCManFM. You can unmount and delete .gvfs, but it
will re-appear after a while. It is annoying, but appeals to both PCMan and
Klaus K will have been of no avail up to now.
Also, FYI, Ubuntu has re-located this annoyance. See:
