Comment (by pbelotti):

 This might be due to a failed check for same indices in a product. Because
 products x*y are convexified using McCormick inequalities that use both x
 and y's indices, if they are equal this happen. There should be an easy
 fix that simply checks for that in the convexification procedure. What
 version are you using (trunk or stable)?
