Description
I've upgraded a Trac instance deployed on Apache in CGI mode. The database upgrade went well, testing in standalone mode looked ok, but with Apache I just got a blank page, no HTTP error, no stacktrace, and nothing in the Apache error.log in debug mode.
I tracked down the issue to cgi_frontend.py where an exception occurs (but isn't propagated for some reason) when calling sys.stdout.write(data):
write() argument must be str, not bytes
Converting the bytes to string fixed the issue:
sys.stdout.write(data.decode('UTF-8'))
