perfview: Format Exception when opening the CPU view on on a Linux Trace.

To Repro

Download https://github.com/deppe/XmlSerializerPerf/blob/master/xmlperf.trace.zip

Open PerfView on it,

Open CPU view.

From the Log we get

I’m experiencing the same issue as @sandeeprawat and @Anteru with the same stack trace. Trace originates from a kubernetes pod and all the data seems intact when viewed using perfcollect.

I’m getting the same issue with .net core 2.1 trace from Linux. Using latest PerfView (2.0.46)

Unfortunately, I cannot share the trace 😦 I’m running into this one here:
