Firefox 4.0 symbol lookup error: /usr/lib/mozilla/plugins/libvlcplugin.so: undefined symbol: NPP_Initialize

[Sam_]

Binary package hint: vlc

Firefox refuses to launch. Bug #722690 is not fixed.
Workaround: I had again to rename the file to libvlcplugin.so-broken in order to launch firefox, although after recent updates.
$ firefox
/usr/lib/firefox-4.0.1/firefox-bin: symbol lookup error: /usr/lib/mozilla/plugins/libvlcplugin.so: undefined symbol: NPP_Initialize
