Bug in refactored SWIG Bindings.


#!/usr/bin/python

import selinux
args = [ "/bin/bash", "--version" ]
selinux.rpm_execcon(0, args[0], args, [ ])

Produces:

Traceback (most recent call last):
  File "test.py", line 5, in <module>
    selinux.rpm_execcon(0, args[0], args, [ ])
TypeError: in method 'rpm_execcon', argument 3 of type 'char *const []'

Version-Release number of selected component (if applicable):
libselinux-2.0.31-3.fc8

James do  you have a nice quick fix for this?
