tracd 1.5.2 --daemonize fails, "TypeError: an integer is required (got type str)"

[stu-trac-@…]

https://trac.edgewall.org/changeset/17483/trunk/trac/util/daemon.py changed daemonize from open to os.open, but didn't convert from Python 'rb' and 'ab+' to os.open flags, result of trying to run tracd -d is:

Traceback (most recent call last):
