Public bug reported:

If mahara user in mysql has been created using mahara wiki guide (grant
all on (databasename).* to 'username'@'localhost' identified by
'password';) everything should work fine, however if some external tool
like 'mysql administrator' has been used to create mahara user
initially, TRIGGER permission might not be granted, which will result in
the error similar to below:

 Could not execute command: CREATE TRIGGER "update_unread_insert_trigger" AFTER INSERT ON "notification_internal_activity" FOR EACH ROW BEGIN IF NEW.read = 0 THEN UPDATE "usr" SET unread = unread + 1 WHERE id = NEW.usr; END IF; END
Call stack (most recent first):
execute_sql(" CREATE TRIGGER {update_unread_insert_...") at /home/ruslan/git/services/vle/mahara/htdocs/lib/dml.php:1757
db_create_trigger("update_unread_insert", "AFTER", "INSERT", "notification_internal_activity", " IF NEW.read = 0 THEN ...") at /home/ruslan/git/services/vle/mahara/htdocs/notification/internal/db/upgrade.php:64
xmldb_notification_internal_upgrade("2009012700") at /home/ruslan/git/services/vle/mahara/htdocs/lib/upgrade.php:374
upgrade_plugin(object(stdClass)) at /home/ruslan/git/services/vle/mahara/htdocs/admin/upgrade.json.php:94

I think upgrade process should be more intuitive and in case of error,
it should provide information on permission-related problem along with
possible solution (e.g. Your database user might not have been granted
TRIGGER permission, please run GRANT TRIGGER on ... ).
