Please run the following command and reproduce this issue, then attach the
output here. It should show what goes on behind the scenes (the communication
between knotifyd or whatever it's called and Banshee).

dbus-monitor --session interface=org.freedesktop.Notifications | grep -v byte

Thanks.

@Chow Loong Jin: your command dbus-monitor --session interface=org.freedesktop.Notifications | grep -v byte does not produce any output when I hit the 'skip this item' button. Is there another way to fetch this output?

Quite weird. How about dbus-monitor
"interface=org.freedesktop.Notifications,type=signal" ?

The output from dbus-monitor "interface=org.freedesktop.Notifications,type=signal" is as follows:
-----------------------------------------------------------------------------------------------------------------------------------------------------------
signal sender=org.freedesktop.DBus -> dest=:1.192 serial=2 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameAcquired
   string ":1.192"
method call sender=:1.15 -> dest=:1.192 serial=922 path=/; interface=org.freedesktop.DBus.Introspectable; member=Introspect
signal sender=:1.12 -> dest=(null destination) serial=566 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=ActionInvoked
   uint32 3
   string "skip-song"
signal sender=:1.12 -> dest=(null destination) serial=567 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=ActionInvoked
   uint32 3
   string "skip-song"
-----------------------------------------------------------------------------------------------------------------------------------------------------------

Does that help?

Looks like the signal was sent twice rather than once. Was that for one click of
"Skip this item" alone? If so, then it's a knotifyd bug.

That was just one click, yes. Do I need to submit this bug to knotifyd?

No need. We'll just use this bug report.

Patch posted to KDE reviewboard:
http://reviewboard.kde.org/r/2485/

Fix committed in kde svn:
http://websvn.kde.org/?view=revision&revision=1070208

Fix released to lucid.

Will this fix be back ported to Karmic at all? Or is there a way to get it into Karmic myself?
