[packagekit] ANother python error

[Richard Hughes]

I don't think this one is caused by me:

Error Value: global name 'ERROR_SIGNATURE_NOT_IMPORTED' is not defined
  File : /usr/share/PackageKit/helpers/yum/update.py , line 19, in <module>
    backend.update(package)
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py , line 856, in update
    self._runYumTransaction()
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py , line 920, in _runYumTransaction
    self.error(ERROR_SIGNATURE_NOT_IMPORTED,"GPG key not imported.")
