healthchecker exception with incomingXdrPerformance stats

Exception when running current health checker on older file. If I comment out the incomingXdrPerformance stat, this goes away.

~/c/code/healthchecker (master)$ ./cbhealthchecker -i ~/c/cust/advertise.com/couchbase/2012-11-19_15-57-27.json
Exception launched when processing counter: incomingXdrPerformance
