            Bug ID: 107995
           Summary: Weird back-quoting in xdg-utils-common.in
           Product: Portland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: xdg-utils
          Assignee: portland-bugs at lists.freedesktop.org
          Reporter: alexl at redhat.com

This code in xdg-utils-common.in seems weird:
https://github.com/freedesktop/xdg-utils/blob/master/scripts/xdg-utils-common.in#L317

copied here:

 elif `dbus-send --print-reply --dest=org.freedesktop.DBus
/org/freedesktop/DBus org.freedesktop.DBus.GetNameOwner
string:org.gnome.SessionManager > /dev/null 2>&1` ; then DE=gnome;

Why are we running dbus-send and then executing its output, after having sent
it to /dev/null.

It seems to get the right result:

$ if `false > /dev/null`; then echo YES; fi
$ if `true > /dev/null`; then echo YES; fi
YES

But, why?
