Whenever knotify tries to display a notification which is connected
with an audio notification, it complains that there is something wrong
with the phonon-vlc backend, and crashes afterwards. Backtrac:

Even if there is something wrong with the phonon-vlc backend, knotify
should not crash.
The VLC error message is "LibVLC failed to initialize. Phonon's VLC
backend failed to start. This usually means a problem with your VLC
installation, please report a bug with your distributor". When I click
on "Details" in this error message box, I see a single random byte.
I see this on current Debian unstable, on two different systems.
I have also filed this upstream as
https://bugs.kde.org/show_bug.cgi?id=297950.
Greetings

Can you please give some sample commands? Cause as of the current time,
I've failed to get any audio output from the command.
