[BRLTTY] Polkit error fills startup log

[Rob]

BRLTTY 5.5, ubuntu server 18.04.
My start up log is full of line after line after line of text that looks like:
May 08 14:23:26 newbean brltty[493]: brltty: unable to connect to polkit: g-io-error-quark (163) Error initializing authority: Could not connect: No such file or directory (1)
This appears over, and over, and over, and ooooover again.
Is this expected behavior?
