Bug description:
  We recently started getting reprots from phone users that their
  devices go into a reboot loop after changing the language or getting
  an OTA upgrade (either of both end with a reboot of the phone)

  after a bit of research we collected the log at
  http://pastebin.ubuntu.com/10872934/

  this shows a segfault of upstarts init binary in the log.c code:

  [    6.999083]init: log.c:819: Assertion failed in log_clear_unflushed: log->unflushed->len
  [    7.000279]init: Caught abort, core dumped
  [    7.467176]Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000600
