Sure.

Slowdown started when I returned from play list editor (directory mode)  
to current playlist and select track from album having errant cover.jpg
Theme is mythmediastream.

Ahh - I was probably not precise in my description. Performance issue is 
only with initial loading of playlist editor screen. When it loads (I 
mean user stat to see playlist editor screen) - all is OK. Issue is that 
loading this screen takes 5-10sec. Some users are telling me "look, it 
hangs")
Of course I'm not talking about "all tracks" view as listing 30k tracks 
doesn't make sense :-)
