I ran into this problem this morning (w/ beta 8). I have rebooted two or three times now, and although Canola now starts for me, it will not find my music. I ran from X-term with the -vvv option and saw an error that it could not access the music database because it appeared to be locked. I do not have time right now to get all the debug text off my tablet into this post, but I wanted to report the problem.

I will also post what may be an important string of events that lead up to this. Last night I fell asleep listening to Groove Salad with Canola. Rather than close Canola, I simply paused the stream playback and set my N800 on my nightstand. I figured it too would fall asleep. This morning when I tried to wake it up, rather than coming out of its sleep state it booted completely from scratch. I don't know how or why it shut down completely--I have seen this a few times before. Perhaps a program (Canola/not Canola?) was preventing the tablet from auto-sleeping and the battery ran all the way down. I am thinking that Canola left some critical file(s) locked because there was not a graceful shutdown.

Will try to get debug messages into this thread. The lock error seems reproducible. But I am very busy today so please excuse the delay. I was sad that I couldn't listen to music with Canola on my ride into work this morning, if that tells you how much I like Canola!
