Hi,
Since the latest Winter release we have had trouble with one of our Visualforce pages that uses a custom Apex controller. The page displays a list of leads with the Most Recently Responded to Campaign Name and the Response Date.  See image below of what it used to look like (But with a Date in the Response Date column):



We are getting the following error on the page: 
     "Invalid CurrencyIsoCode for SObject CampaignMember"

If we hide the Campign Response Date column from the page, or use a different field then the page renders ok. It seems to only error when we are picking a field from the CampaignMember object.

Is someone able to help us?? I haven;t got a response from Salesforce yet and am rather perplexed about this error as we dont really use the Currency fields in our org, everything is in USD.
I have included the snippets of VS Page code and Apex Controller code that seem relevant.
