yes. here is the code that fails. I don't understand why the unbound
method. what is really weird is that when I singlestep through the
code, it never seems to call filter_test. it is like the method never
existed.
File "C:\Python24\lib\logging\__init__.py", line 539, in filter
if not f.filter(record):
TypeError: unbound method filter() must be called with filter_test
instance as first argument (got LogRecord instance instead)
