amaroK: libvisual visualisations problem

[Pavel Troller]

Hi!
  For some time, I cannot see any visualisations powered by libvisual. Whenever
I try to start any of them, its window appears for a short while but then 
immediately disappears again and that's all.
  I just updated libvisual, libvisual-plugins and amaroK from CVS. When amaroK
is started from konsole, every attempt to run a libvisual visualisation produces
the following line:
libvisual WARNING: /opt/kde3.3/bin/amarok_libvisual: visual_plugin_get_list(): Failed to add the /opt/sound/lib/libvisual/transform directory to the plugin registry
  There is no /opt/sound/lib/libvisual/transform directory at all, there are
only input, actor and morph directories present at the above path. I can see
all the visuals from the actor directory in the amaroK visualisation plugin
window. However, I don't know whether this line is important at all.
  Other visualisations, including ogl_spectrum, work perfectly.
  Where should I look for the problem ? I believe it's my local installation
problem.
                           With regards, Pavel Troller
