[Plugin: WordPress Backup to Dropbox] Version 1.2.2 No Longer Backing up Database

I’m also not seeing a sql dump generated on the server, but the rest of the files are backed up properly.

I’m getting these error message in my WP debug.log which look related. (Log messages slightly modified to keep my system info private):

PHP Notice: Undefined index: dump_location in /wp-content/plugins/wordpress-backup-to-dropbox/Views/wp-backup-to-dropbox-options.php on line 43

WordPress database error Table 'MY_DB_NAME.wp_sitecategories' doesn't exist for query SHOW CREATE TABLE wp_sitecategories made by do_action_ref_array, call_user_func_array, run_dropbox_backup, WP_Backup->execute, WP_Backup_Database_Core->execute, WP_Backup_Database->backup_database_tables

WordPress database error Table 'MY_DB_NAME.wp_sitecategories' doesn't exist for query SELECT COUNT(*) FROM wp_sitecategories made by do_action_ref_array, call_user_func_array, run_dropbox_backup, WP_Backup->execute, WP_Backup_Database_Core->execute, WP_Backup_Database->backup_database_tables

This is happening only on a blog within my WP network with 1.2.2. It works with 1.2 on that blog and the 1.2.2 code appears to work on a standalone blog as well.
