Bug#1093378: xfce4-session: xflock4 now uses gdbus without depending on libglib2.0-bin

[Benjamin Kaduk <kaduk@mit.edu>]

Package: xfce4-session
Version: 4.20.0-1
Severity: important
X-Debbugs-Cc: kaduk@mit.edu

It looks like upstream 4.19.1 changed xflock4 from getting a lock command via
xfconf-query to using a D-Bus method to lock the screen.  This means it calls
gdbus directly, but gdbus is in libglib2.0-bin which is not listed in
debian/control at all.  Indeed, it's not installed on my system at all, so
locking the screen by menu or xflock4 directly does nothing (locking screen by
timeout does work).

I had considered making this 'serious' but xfce4-session does many things
other than locking the screen so maybe 'important' is right.
