Ok dudes, there is no way in hell that VLC can avoid limitations of Xlib.

This is due to Amarok not calling XInitThreads() which is required when multiple threads in the same process use Xlib.

As a (poor) alternative, Phonon-VLC would need to pass "--no-xlib" to libvlc_new(). However this would disable some useful Xlib-dependent plugins inside of LibVLC. Or Phonon-VLC could explicitly depend on LibVLC >= 1.1.6, which automatically but unreliably detects the need for "--no-xlib". Anyway, functionality will still suck due to avoiding Xlib.

In any case, this is not a VLC bug.

This bug was fixed in the package vlc - 1.1.5-3ubuntu2

---------------
vlc (1.1.5-3ubuntu2) natty; urgency=low

  * Add 0101-pulse-Disable-xlib-in-pulse.-libpulse-now-uses-xcb-o.patch
    from upstream, use xcb instead of xlib, stops crashes with pulse LP:
