Dispatching a method using PyobjC Selectors/Methods

[sapsi]

Hi,
I am writing a SIMBL plugin for Mail.app, so far it loads and the
correct method has been swizzled. However, i would like to call the
original method and that is where the problem lies.

If you could see the code(below), in console.app, i get the following
error because of old(x)
"
2007-06-26 03:42:04.053 Mail[2600] *** NSRunLoop ignoring exception
'exceptions.Typ eError: 'int' object is not callable' that raised
during posting of delayed perform with target 5bd1b10 and selector
