Error communicating with Spreedly

[ganders]

I'm getting the following error intermittently when communicating with spreedly. It's a Ubuntu 10.04 box running rails 3.0. I'm getting it in multiple places but the line of code for this particular incident is:

def get_spreedly_plan_by_name(plan_name)
RSpreedly::SubscriptionPlan.all.each do |spreedly_plan|
if spreedly_plan.feature_level == plan_name
return spreedly_plan
end
end
nil
end

Any help is V E R Y appreciated, I'm pretty much at a loss on this one.
