Title:
  zram-config is not working on non-English locales in vivid

Status in zram-config package in Ubuntu:
  Fix Released
Status in zram-config source package in Vivid:
  In Progress

Bug description:
  [Impact] 
   * People using some non English locale, zram devices are not loaded
   * The service fails to stop and unloading zram module as well

  [Test Case]
   * Install the new zram-config package
   * Reboot and check that the zram devices are created:
  $ swapon -s
  -> returns some zram devices
   * $ sudo systemctl status -l zram-config.service
  -> no error
   * Stop the service:
  $ sudo systemctl stop zram-config.service
   * $ sudo systemctl status -l zram-config.service
  -> no error
   * swapon -s
  -> no more zram device listed

  [Regression Potential] 
   * Services loading change may impact English-local user. However, the fix has already been confirmed to be working on wily.
   * Stopping the service was already failing on unloading the module, so no additional regression is possible there.

  ---------------------

  
  The zram-config package install works without errors, but at swapon -s, no zram devices are listed.

  $ dmesg | grep zram
  [   26.933769] zram: Created 4 device(s) ...

  $ swapon -s
  Filename				Type		Size	Used	Priority
  /var/cache/swap/swap0                  	file    	4194300	223296	-1

  This problem exist on my notebook and I can recreate it on a fresh
  15.04 vm install.
