So, this bug affects some derivatives of Ubuntu, if derivatives includes apt-line of DIST-SUBNAME(such as "natty-non-free") , the apt-clone breaks their sources.list files.
* We can reproduce only these situations:
- Install to pre-formatted partition (that has already ext4-formated with gparted).
- "manually partitioning" selected at Ubiquity.
- In these situation, Ubiquity invokes apt-clone.
- apt-clone is crashed. the crash is reported problem.
* We could not reproduce in pure clean-install process.
