Hi Peter, Thanks for reporting this issue.
>From the exception stack, it seems there's indeed a problem. However, I'm not able to reproduce this issue on my machine, and I guess that's why this is not discovered before the release. Could you help share some more details (and maybe screenshots) on how this issue is triggered?
