I discovered that this issue can be 'fixed' (or rather, hacked around)
by explicitly checking for the existence of the class before calling
the callback. In other words, this was failing:
$result = call_user_func_array("MyClass::MyMethod", array());
But, this works:
class_exists('MyClass');
$result = call_user_func_array("MyClass::MyMethod", array());
Ugly, but at least it keeps me moving forward for now.
