That's an error trying to open the database file. Make sure your calibre library is on a proper native filesystem, not a networked filesystem, not a folder shared by some file syncing program, not a filesystem that has buggy linux drivers, not a disk that is failing, etc.

Thanx Kovidgoyal for putting me on the right track.
I solved the problem deleting the file : metadata_db_prefs_backup.json in my Calibre Library folder.
