Bug#950174: gvfs-udisks2-volume-monitor.service crashes: No GSettings schemas are installed on the system

[Pascal Dormeau]

Hello,

I do not know if the following can help. So just in case.
I met the same problem recently on a xfce4 setup. Digging in the
bug reports I found this one that matches the same error messages I had.
I finally solved my problem noticing that it happened after modifying
the XDG_DATA_DIRS variable and after some some paths in that variable
were deleted on my system. Removing the non-existing
paths from XDG_DATA_DIRS variable solved my problem.
Therefore, it might be worth verifying if all paths in the XDG_DATA_DIRS
actually exit (or can be accessed).

Best regards
Pascal
