@Dantounet: seems to be an I/O error, according to the error number (it's the sqlite error returned). Maybe the hard drive (or… SD card ? don't tell me you're using btsync on an sd-card…) has some problems. Also, the RPi has an unreliable USB connection - this may create some problems if you have an USB hard drive… For such a use, maybe the cubieboard[1] is better, as it has a dedicated sata port, and it's a bit more robust… Have a look at system logs (such as dmesg), it may give you some more information.
