I am having exactly the same problem on ubuntu 18.04. It started after I
installed fprint for the fingerprint reader, back on 16.04. I decided to
wait until I'd upgraded to 18.14 before trying to track it down.
I have reinstalled bluez to no avail.
** Changed in: bluez-utils (Ubuntu)
I am having this problem with a fresh install of 10.04, fully updated.
This problem ALWAYS occurs. Rebooting doesn't fix it. I have all
permissions set in my account. I can't mount anything or reboot from the
GUI, I have to su and do it from the command line.

Same problem with a new install of 10.04 LTS on a laptop. No combination
of rebooting or other fiddling suggested on the forums has helped.

Public bug reported:
Binary package hint: gnome-system-tools
From the Services settings dialog (services-admin), I accidentally
clicked the box for System Communication bus (dbus) instead of
Printer service (hplip) directly above it. This happened because the
dialog had stopped responding
Followup: there's a lot of messages in various forums that look like the
same general problem, with people proposing solutions like reinstalling
various sets of packages.
In the interest of getting someone something up for people searching for
the same problem... the workaround is to run sudo
