Amarok2 system tray icon missing

Hi Trinity users! I've recently switched from KDE 3.5.10 (Debian Lenny) to KDE 4.4.5 (Debian Squeeze) and was really disappointed by KDE 4 slowlyness (qt4/nvidia driver issue...?). This morning I decided to give a try to Trinity 3.5.12 and I feel... better! Things are almost perfect, fast, etc. just like it was in KDE 3.5.10, even KDE 4 applications appears to run fine (and so, much faster than under KDE 4 itself) However, I wonder if Amarok2 system tray icon is compatible with the KDE3/Trinity system? I've tried various KDE 4 apps that uses system tray icons, and they were ok with that (klipper 4.4.5 for example). Have you got an answer...? Thanks! Nicolas.
