I was trying to install a package from Livna and there came this error:

The package was: [xine-lib-extras-nonfree-1.1.1.12-2.lvn9]

Error Type: <type 'exceptions.TypeError'>
Error Value: object of type 'instancemethod' has no len()
  File : /usr/share/PackageKit/helpers/yum/install-packages.py , line 19, in <module>
    backend.install_packages(packages)
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py , line 226, in wrapper
    func(*args,**kwargs)
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py , line 949, in install_packages
    self._runYumTransaction()
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py , line 1151, in _runYumTransaction
    hex_fingerprint = "80740e5" * len(fingerprint) 138481712ple(map(ord, fingerprint))

Any hint about dealing with this issue??

Thanks
