If I send a transient notification to the notification-daemon, it is displayed but after it disappear no more notifications are displayed, transient or not.

Example:

(1) $ notify-send "bla" "blub" # working
(2) $ notify-send --hint=int:transient:1 "bla" "blub" # working
(3) $ notify-send "bla" "blub" # not working
(4) $ notify-send "bla" "blub" # not working
(5) $ notify-send "bla" "blub" # not working, after the notification of line 2 disappeared

Looking at the dbus-monitor output, for the above example, I see the method call for the first 4 calls, but not the last one. So it seems to be related to what happen in the `on_bubble_destroyed` callback, but I've not went further as I don't have time to setup my machine to debug this.

I've tried other hints and didn't noticed any problem with them.

I'm using ArchLinux with gnome-session and xmonad (it also happen with the gnome desktop). Here's the relevant library information:

 * extra/notification-daemon 0.7.3-1
 * extra/libnotify 0.7.4-1
