same day, same issue.
yesterday it was ok, approx. 1'500 songs in library. all i did between was a backup on sd card and then installed the newest fennec alpha.

rootfs is 83mb; home 1gb; mydocs 21gb; mmc1 4gb free

tried to reboot two times but didn't change anything. next step is removing fennec alpha...could this be related?

thanks in advance.
