I just make the a test, I'm on Opensuse 11.04 and KDE47 stable repository  
and things seems to be ok here. My main lens still not here (sigma  
17-70mm) but it's due to the fact it is not here I think, since I see a  
various manufacturer and lens references (included Canon's ones).

Could be the matter in the packaging ?
