Hi Tom,

My preferences pane has a helper app that repairs itself (sets the 
setuid bit) and executes a couple of administrative tasks that require 
root access using AuthorizationExecuteWithPrivileges, which is the 
only way that the bundle could be modified after running the first 
time after installed.

I hadn't seen any related messages on the console before, but after 
removing the cache file this is what I get:

18-01-08 14:55:35 System Preferences[5377] Preference bundle "/Users/
carlosoliva/Library/PreferencePanes/DrQueue.prefPane" is misplaced, 
ignoring...

Googling around about this message doesn't seem to show up anything 
relevant.

Thanks for your help.

Best regards,
