AV exception in InstanceSelector.IsProductMatch

[heaths]

Using 2.2.7+g44e1483649 [query version 1.15.51.49582] while install was running, an access violation exception occurred.

From Watson crash dump:

I was able to reproduce with no "product" property and no "type": "product" object in the "packages" array at least as far back as 1.0.71 where I stopped trying to repro. Could be a chance in the query API.
