I'm currently doing some development to get cisco switches under puppet management. Some of those devices report their operatingsystemrelease as '12.2(55)SE5'. When trying to push those facts to foreman with the push_facts script, the first push emits the following message and fails to populate the overview values like OS and version:

Started POST "/fact_values/create?format=yml" for 10.1.105.39 at 2013-04-04 13:47:52 +0000
  Processing by FactValuesController#create as YML
  Parameters: {"facts"=>"[FILTERED]"}
No smart proxy server found on []
Failed to save switch.example.com: Validation failed: Minor is not a number
Rendered text template (0.0ms)
Completed 200 OK in 175ms (Views: 0.9ms | ActiveRecord: 67.2ms)

I've confirmed that (manually) setting the operatingsystemrelease to '12.2.(55)SE5' results in a properly populated host.
