.. or unless __call() returns Array of instance names.
I'd say there is no bug, 'cos your overloaded __sleep() method indeed
returns wrong data.

Description:
------------
If an object is overloaded (with __call()), then serializ'ing the
object will fail unless __sleep() is defined.
It would be far clearer to either
a) - force __sleep to defined on overloaded objects (E_WARN?)
b) - dont call __call() with the __sleep() request.
Reproduce code:
---------------
class a {
public $a = 4;
function __call($a,$b) {
return "unknown method";
}
}
$b = new a;
echo serialize($b);
Expected result:
----------------
Warning: __sleep is not defined on an overloaded object with __call()
Actual result:
--------------
Warning about unexpected return value to __sleep() and an empty string
output from serialize()
