BTW, you can simply use print_r($this->_ids, true) to get a printable  
copy of the array values - or better yet, use  
Horde::debug($this->_ids); and this will output to a file named  
horde_debut.txt in your server's tmp directory.

This doesn't explain why the flip doesn't work. They are both arrays.  
The error complains that the value is NOT an array. We need both the  
value of the ids array as well as the backtrace when it doesn't equal  
an array. You can get a backtrace via either debug_bactrace() or just  
use Horde::debug which automatically generates it.
