Unable to open trace generated via cpp bindings

[graphicsMan]

I'm attempting to open a trace generated via cpp bindings. I was able to open a simple single-scope trace generated from the main thread, but when I use it from multiple threads, I get this error: "Type error: cannot read properly 'a' of null"

Is this a known issue? If so, is there a workaround?
