Same problem here. Backtrace looks exactly the same! Amarok is from yesterday and Phonon-VLC from today, both from git. KDE 4.6 beta2 // Qt 4.7.1 // VLC 1.1.5 from OpenSuSE Packman Repo I don't know, if it's relevant, but I'm using Pulseaudio.
Confirmed by duplicate. The problem apparently is in libvlc. Can't confirm this here, using current Amarok 2.4-git and phonon-vlc-backen from git, VLC built from stable branch 1.1.4-git, KDE 4.6 beta 2 on Kubuntu 10.10. Let's check what our VLC guy thinks about this.

as an additional comment - after switching the vlc itself from the original videolan repository to the vlc version in Packman/Opensuse 11.3 - the backend is stable and works - also knotify does not crash anymore. The phonon-backend-vlc Version is the same 0.3.1-1.1 from KDE:Unstable:Playground Repo for Opensuse 11.3
Yeah, a crash in libvlc_media_player_new means that VLC does not find any plugins, which is really a packaging issue. If someone could talk to the opensuse team, that would be great. Leaving the bug open, so we do not forget to nag them until it is fixed ;)

Actually a terminal output would be very nice, ideally with the following environmental vars: export PHONON_DEBUG=5 export PHONON_VLC_DEBUG=5

Your crash is coming from a broken setup (apparently your vlc plugins are built against a different version of libvlc (supposedly 1.x as you are using 1.2). Nothing we can do about that though. It confirms that the crash is due to missing (or in your case unloadable) plugins.
Setting priority and stuff to minor as it is not technically a bug in phonon-vlc.
I haven't the slightest idea how my vlc plugins are built - I just download and install opensuse 11.4 beta's and RC's.
Reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise.

Just a heads up, in 0.4.0 a warning appears for GUI applications when libvlc fails to initializes. Not the most perfect of solutions, but good enough for now.

Is this still valid for the latest 0.6.2 version of the vlc backend? Apparently all reports are about prior versions. If this is still reroducible we would need a more recent backtrace.
with vlc 2.0 it does no longer crash but correctly error out on _new and phonon displays an error message accordingly. also from a quick test it seems the application also will not crash after that but simply not produce any output, which is the intended behavior. resolved from phonon pov
