db_select error in function theme_casetracker_comment_changes($variables)

The error is in the first case clause of the switch statement that appears in the function theme_casetracker_comment_changes($variables), which is in the casetracker.module file.

The code reads:

$new_title = db_select('node', 'n')
->fields('n', array('node'))
->condition('n.nid', $new->pid)
->execute()
->fetchField();

There is no field named 'node', and this results in an exception being thrown (and uncaught).

The above statement needs to be replaced with:

$new_title = db_select('node', 'n')
->fields('n', array('title'))
->condition('n.nid', $new->pid)
->execute()
->fetchField();

Unfortunately I am not equipped to provide you with a patch.
