Re: [cclib-devel] strange logger bug

Sorry, just checked. clean() doesn't remove the logger, nor should it.
If you parse the same file a second time (e.g. this is common with
GaussSum users following a geometry optimisation) you still want a
logger.

The problem you found occurs if you create two instances of parsers
with the same name. We either ignore this problem, or implement some
complicated way of tracking file names. Perhaps if we only create the
logger when parse() is called, then we can remove it when clean() is
called.
