This is indeed a bug! And a pretty serious one; it's explicitly documented to work otherwise. Please file it. The reason that this happens is that the 'namespace' field is filled out by the descriptor (__get__ method) of the `Logger` object when it is bound to `self`. You can work around this in the meanwhile by changing your example to be like so: import sys from twisted.logger import (Logger, textFileLogObserver) observer = textFileLogObserver(sys.stdout) class MyClass: @property def log(self): return Logger(namespace="ad_hoc", observer=observer, source=self) def __init__(self): self.log.info("MyClass.__init__ called!") def __del__(self): self.log.info("Bye!") obj = MyClass() -glyph
