Did PM Stage Potty Protest in Brazil?

If true, this bodes really well for the strengthening of trade ties between Brazil and Canada.

According to a Brazilian report, Prime Minister Stephen Harper locked himself in a bathroom when discussions with President Dilma Rousseff went awry over the timing of toasts during a state lunch. The Brazilian news website Folha says Harper, in Brasilia for trade talks, took to the bathroom of Brazil's foreign minister in a mini-protest over the toast issue, and refused to come out until his South American counterparts relented. The alleged use of this stalling tactic (get it? stalls? bathrooms?) follows a previous protocol scuffle between the Brazilians and Canadians, as the former refused to have media photographers attend a photo op. Of course, the Prime Minister's Office denies this happened, but as you may recall, Harper missed a group photo at the G20 meeting in London in 2009 due to an extended trip to the bathroom.
