Thanks for taking the time to report this bug and helping to make Ubuntu better. Looking at your package installation log file I believe you may have an older version of python installed, for example python2.4 (or python2.4-minimal), which is causing this issue. Could you check and if it one is installed, and you aren't using it, please remove it and try reinstalling the package? Thanks in advance.
