This is a bug in python-apt and should probably be reported in either Ubuntu or Debian depending on which distro you're using in order to get it fixed.

f1cf457edb2a9552adf82d72541af69487f897f4 at least makes an attempt to handle the error from the Bcfg2 perspective, but it'd be a good idea to get this fixed upstream as well.

Hi sol,

thanks for looking into this. It turns out that there was a syntax error in the preferences file so my bad. However, the handling of the error would be a nice addition.

Thanks =]
