When an array with NULL Value is stored in the Horde prefs, Nag thows  
an PHP warning: 'array_flip(): Can only flip STRING and INTEGER values!'

This is caused by an erroneous Horde Pref like 'a:1:{i:0;N;}'.  
Deserialized, this array contains a Null Value and is this not  
flippable.

When loaded from the DB and deserialized, the array should be validated with
$cs = array_filter($cs); before it is used.

This is similar to
