Before I knew about BDB's ACID capabilities, I thought that it is susceptible to corruption. I now think it is unlikely for BDB to get corrupted through interruptions such as power outages, process crashes etc. That said, I actually can't think of a simple way out of your situation. As worst case option, insert the SD card of your FreedomBox in a GNU/Linux machine and remove the /var/lib/abl/* files. If your FreedomBox is on a regular machine, boot into rescue mode and delete the files. If the BDB database is corrupt I would suspect that your disk has developed errors. Check the disk for bad sectors just to be sure. -- Sunil
