Indeed. It works fine with org.gtk.Private.GduVolumeMonitor as service,
but with "some.service" it fails. Why?

It's not a Z. One of our MUA altered this.
On the first try it's " ^H\330"
On the second try it's "Z^B"
On the third try it's "\300#\264"
…
(I register then unregister to make a try)

Oh yes I'm sure of that. :)

Yeah. I start emacs-snapshot, then register then call
`dbus-list-hash-table', it messages:
(((:session "org.freedesktop.Notifications" "ActionInvoked")
(":1.129"
"org.freedesktop.Notifications" "/org/freedesktop/Notifications"
notifications-on-action-signal
"type='signal',interface='org.freedesktop.Notifications',member='ActionInvoked',sender=':1.129',path='/org/freedesktop/Notifications'"))
((:session "org.freedesktop.Notifications" "NotificationClosed")
(":1.129" "org.freedesktop.Notifications"
"/org/freedesktop/Notifications" notifications-on-closed-signal
"type='signal',interface='org.freedesktop.Notifications',member='NotificationClosed',sender=':1.129',path='/org/freedesktop/Notifications'"))
((:session "org.gtk.Private.RemoteVolumeMonitor" "VolumeAdded")
(""
"some.service" "/org/gtk/Private/RemoteVolumeMonitor" identity
"‚\x02\x01")))
In case one of our MUA will change the last string on the last line it
shows:
"^A\202^F^B^D^A"
Then I call unregister it yells:
Debugger entered--Lisp error: (dbus-error "Unable to append argument" "\202\x02\x01")
dbus-call-method(:session "org.freedesktop.DBus" "/org/freedesktop/DBus" "org.freedesktop.DBus" "RemoveMatch" "\202\x02\x01")
Where the last string is obviously the same as I talked about above. :)
