Sun Apr 12 08:05:27 UTC 2015

I have following error if I ask amarok to re-do all the database
GREPME MySQLe query failed! (1062) Duplicate entry 'amarok-sqltrackuid://a9c8f5ea2fba51824b1a578ecd5f5e2e' for key 'images_name' on UPDATE images SET path='amarok-sqltrackuid://a9c8f5ea2fba51824b1a578ecd5f5e2e' WHERE path = 'amarok-sqltrackuid://02b6692e857772453130ec4c9a879677';

All my tracks are locally stored mp3s. How to manually query the DB from command line to get more informations?
