Running Metamorphose 2 0.6.3 (Downloaded from SVN Head 16/09/09) on Ubuntu 9.04 with Python 2.6.2 and wxPython 220.127.116.11.
This is what is printed to the terminal when Metamorphose attempts to generate the new names:
Traceback (most recent call last):

onlyShowChangedItems = main.prefs['onlyShowChangedItems']
I get the same problem running the installed deb of 0.6.3 from the website, but I haven't updated that since the last time I was able to use metamorphose 2 without any problems maybe it's an issue with an updated python or wxpython package as I can't remember if those have been updated since I last used it successfully.
