[mythtv-users] No current database version?

[Kevin Ross]

This part here looks like a clue:

2010-02-19 21:27:20.921 Backing up database with script: '/usr/share/mythtv/mythconverg_backup.pl'
2010-02-19 21:27:21.157 DBUtil Error: Error backing up database: /usr/share/mythtv/mythconverg_backup.pl /tmp/mythtv_db_backup_conf_5XfF1E (512)

It can't even back up the database, which shouldn't depend on anything mythtv-specific.  Can you run the mysqldump command manually, without the 2>/dev/null at the end, and see if it outputs any errors?
