VLC cannot open files on SMB shares when running in LXQt

Hi,

VLC 2.2 cannot open files on SMB shares when running in a LXQt 0.9 desktop environment.

Error log:

-- logger module started --
smb error: open failed for 'nas.local/(…).mp4' (Permission denied)
core error: open of `smb://nas.local/(…).mp4' failed
-- logger module stopped --

It looks like a permission problem, but it works in KDE.

Regards, Ettore
