M6 SL stop playback problem

Hi to everybody.

I have bought a M6 SL (firm 2.004.6) a few days ago. It is great but sometimes when I am listening to an album (random mode) the player stops without ending the album.
It happens with a random number of songs played. Sometimes it stops on first song, sometimes on third one, etc.

Anybody has this problem too? How can i fix this?

Thanks for the answers.

Yes, my M6 SP does this too.
I think it is a bug in firmware there isn't solved yet.
