Update virgin F9: yum/dbus TypeError

[Patrick]

Hi,

I just installed F9 on a box and did a yum update. 700+ packages later I 
see the following error:

  Cleanup : gtk2           ######################### [885/885] <-last pkg
ERROR:dbus.connection:Unable to set arguments () according to signature
u's': <type 'exceptions.TypeError'>: More items found in D-Bus signature

TypeError: More items found in D-Bus signature than in Python arguments


My googling came up empty so I wonder if this error is a known issue and 
if I should bugzilla this. And how I can possible fix this error if it 
impedes the correct working of yum.

Suggestions most welcome.

Thanks and regards,
Patrick
