log formatting error with string and bytes concatenation

[ARashitov]

About

When I want to format logs I face error[Appendix A] telling that concatenate of str and bytes is impossible, but it works when I remove parameter: formatter=text in my log.ini file[Appendix B]

Appendix A | traceback

"Waiting for application startup."

I am in fact facing the same issue. Thank you for posting this.

Had to write custom handler to fix this problem.
