Comment 11 for bug 1309447

I pushed a branch lp:~mvo/apt-clone/lp1309447 that contains a testcase, however, I can only make it work if:

http://bazaar.launchpad.net/~mvo/apt-clone/lp1309447/view/head:/tests/test_lp1309447.py#L11

the locale is set to something unsupported or non-utf8, i.e. if the sys.getfilesystemencoding() is not utf8.

So its worthwhile to try to find out if something is unsetting LANG or LC_ALL when update-manager is run.
If its a common problem we should probably also add a workaround like:
