Seem to have destroyed pybliographic

I'm a big big pybliographer fan, but I seem to have screwed it up.

I rather foolishly attempted to edit the medline import filter (via
preferences) and since then have been unable to run pybliographic
(v1.2.5-1 installed via ubuntu 5.10 apt-get):

        ben@nutmeg:~$ pybliographic &
        [1] 9762
        ben@nutmeg:~$ Traceback (most recent call last):
          File "/usr/bin/pybliographer", line 155, in ?
            Config.load_user ()
          File "/usr/share/pybliographer/Pyblio/Config.py", line 337, in
        load_user
            set (item, changed [item])
          File "/usr/share/pybliographer/Pyblio/Config.py", line 152, in
        set
            ConfigItems [key].set (value)
          File "/usr/share/pybliographer/Pyblio/Config.py", line 49, in
        set
            raise ValueError, \
        ValueError: value of `medline/mapping' should be of type
        Dictionary (String, String)

I deleted all the configuration files in my HOME directory and in
usr/local/pybliographer, and also ran:
        apt-get --purge remove pybliographer
        apt-get clean

Then:
        ben@nutmeg:~$ sudo apt-get install pybliographer

However, when I try to reinstall pybliographer, the error returns.
        
My questions are what went wrong and is there a solution?
It seems that linux is reusing previously selected package, does that
mean that the faulty config files that I screwed up are alive and well
somewhere?

My thanks in advance to anyone who can help me out.
