blogtk crashes on start

If a previously version of BloGTK have created a "~/.BloGTK" directory, then the application crashes on start:

cdf@sipuofare:~/Projects/blogtk$ python blogtk2.py
Got configuration directory
Traceback (most recent call last):
  File "blogtk2.py", line 512, in <module>
    blogtk.main()
  File "blogtk2.py", line 167, in main
    self.configReader = config.ConfigReader()
  File "/home/cdf/Projects/blogtk/config.py", line 49, in __init__
    self.tree = ElementTree.parse(self.configFile).getroot()
  File "/usr/lib/python2.5/xml/etree/ElementTree.py", line 862, in parse
    tree.parse(source, parser)
  File "/usr/lib/python2.5/xml/etree/ElementTree.py", line 579, in parse
    source = open(source, "rb")
IOError: [Errno 2] Nessun file o directory: '/home/cdf/.BloGTK/config.xml'

my solution is to write:
rm -rf /home/cdf/.BloGTK
