Starting to see these errors myself as well as camera freezing. Will try disabling HW acceleration. Current version 5.2.9.12
Ugh, that's not good. My problem completely resolved when updating to the latest version shortly after posting my concern. Ken confirmed it was a bug that he squished with the subsequent release. If it's really come back with the latest, that's unfortunate. Make sure you send an email to Ken with that snippet from your logs. Maybe he can knock it out again.
I have noticed that some bugs have a tendency to recur many revisions after their fix. I wonder what kind of development track he's using where code from older builds might inadvertently get put back into the latest releases...
