Flood of error messages as soon as the camera opens

[Tsabary]

As soon as I open the camera fragment that hosts the preview, my logcat starts writing a flow of repeating error messages that don't stop. This is the messages

Does camera work properly?

[Tsabary]

It does but the unstoppable stream of errors is extremely abnormal. I'm talking so fast the if it wouldn't have been the same message I would not have been able to read even a word as it goes.

This doesn't look connected to FA. Simply a device lower level log
