	apt-get install decompyle

4. Open file /usr/lib/python2.4/site-packages/decompyle/Scanner.py with editor

	nano /usr/lib/python2.4/site-packages/decompyle/Scanner.py

5. Change line 58

	self.__pyversion = float('%d.%d' % version_info[0:2])

to

	self.__pyversion = 1.5 ## float('%d.%d' % version_info[0:2])
