I added a test case and regression analysis to the description of this
bug and I also managed to make a patch file with the solution I
described before.

Title:
  Software Center doesn't start on systems in Esperanto

Status in software-center package in Ubuntu:
  Triaged

Bug description:
  When I start the Software Center it immediately gives me a fatal error
  on my fresh 15.10 installation in Esperanto.

  I got the following traceback when I tried to start the software-
  center from the terminal: http://paste.ubuntu.com/12972133/

  I looked at the traceback and I noticed the error occurred in the file region.py.
  In the method _get_region_dumb we try to split the variable loc with the delimeter "_", but the input string does not contain an underscore in the first place. The variable loc only contains "eo" at this point, since Esperanto is not connected to a certain country there is no country code.

  I managed to fix the method _get_region_dumb by adding a try/except
  statement, but I am not able to do a pull request myself as I am not
  really an expert in Bazaar and branches.

  Could somebody update the method _get_region_dumb in region.py and replace it with the following or an other similar method: http://paste.ubuntu.com/12972109/
  I only added the last try/except statement.

  [Impact]
  This bug will prevent the starting of the Ubuntu Software Center on systems installed in the language Esperanto. The fix is so trivial that backporting would be justified.

  [Test Case]
  1) Download an Ubuntu flavour.
  2) Choose the language Esperanto in the installation wizard.
  3) After instalation is complete, start the Ubuntu Software Center (EO: Ubuntu-programarejo).
  4) Nothing happens.
  5) Open the Terminal (EO: Terminalo).
  6) Type "software-center" and press enter.
  7) You will see a traceback, similiar to the one in the bug description.
  8) Apply the patch provided with the bug report.
  9) Now you can start it normally and with the terminal.

  [Regression Potential]
  I do not think there is any way my fix could go wrong, but maybe other people have different opinions about that here.
