Title:
  upstart file bridge sets FILE to glob pattern instead of specific file

Status in Upstart:
  Invalid
Status in “upstart” package in Ubuntu:
  Invalid

Bug description:
  I've made a modification to the update-notifier crash notification
  upstart user job such that it looks like this:

   $ cat /usr/share/upstart/sessions/update-notifier-crash.conf
  description "Notification regarding a crash report"
  author "Brian Murray <brian at ubuntu.com>"

  start on (
      file FILE=/var/crash/*.crash EVENT=create
  )

  env FILE=NULL
  instance $FILE

  script
  DATE=$(date)
  echo "$DATE crash report $FILE detected"
  CRASH=0
  /usr/share/apport/apport-checkreports || CRASH=$?
  SYSTEMCRASH=0
  /usr/share/apport/apport-checkreports --system || SYSTEMCRASH=$?
  if [ $CRASH -eq 0 ]; then
      /usr/share/apport/apport-gtk
  elif [ $SYSTEMCRASH -eq 0 ]; then
      # not in admin group return
      ADMIN=0
      groups | grep -qE "sudo|admin" || ADMIN=$?
      if [ $ADMIN -ne 0 ]; then
          exit 1
      fi
      # be nice and always ask first before firing up pkexec
      /usr/lib/update-notifier/system-crash-notification
  fi
  end script

  $FILE is set to /var/crash/*.crash instead of to /var/crash
  /_usr_bin_d-feet.1000.crash like I would expect.  Subsequently, if you
  perform the following test:

  1) (d-feet &); sleep 3; killall -SEGV d-feet
  2) wait for apport crash dialog to appear
  3) DISPLAY=:0 xeyes &; PID="$\!"; sleep 3; kill -SEGV $PID

  You will not receive a second apport dialog for the xeyes crash
  despite there being a crash file in /var/crash/ for xeyes.
  Additionally, it may be interesting to note that the job log file is
  named '~/.cache/upstart/update-notifier-crash-
  _var_crash_\*.crash.log'.
