Re: [cclib-devel] strange logger bug

This is a "feature" of the logger (yes, I agree it's annoying, but
it's not a bug). The problem is that now you have two loggers both
doing the exact same thing. Loggers are distinguished by their names;
so if you parse the same file twice, without using clear() (which I
hope deletes the logger), you get this effect.
