  multiple scancodes for special keys on Acer P453-MG

Status in The Linux Mint Distribution:

Bug description:
  On my new Acer TravelMate P453-MG notebook the special keys (euro-key, dollar-key) are not working. According to "https://wiki.ubuntu.com/Hotkeys/Troubleshooting"; this is a bug of type 4b, i.e. too many keypress events for a key. I cannot find why/where this happens because of a lack knowledge. When I hit one of these keys I expect to get just one scancode/keycode.
  Pls give some hints on how to narrow it down.

  What happens:
  "sudo showkey -s" returns
  "^[[2;3~^[[4~^[[1;3B^[[1;3A0x38 0x52 0xd2 0x4f 0xcf 0x50 0xd0 0x48 0xc8 0xb8" for the euro-key and
  "^[[2;3~^[[2;3~^[[6;3~^[[1;3C0x38 0x52 0xd2 0x52 0xd2 0x51 0xd1 0x4d 0xcd 0xb8" for the dollar-key.

  "sudo /lib/udev/keymap -i /dev/input/event4"
  "scan code: 0x38   key code: leftalt
  scan code: 0x52   key code: kp0
  scan code: 0x4F   key code: kp1

  scan code: 0x50   key code: kp2
  scan code: 0x48   key code: kp8" for the euro-key and

  "scan code: 0x38   key code: leftalt
  scan code: 0x52   key code: kp0
  scan code: 0x52   key code: kp0

  scan code: 0x51   key code: kp3
  scan code: 0x4D   key code: kp6" for the dollar-key.

  BIOS is up to date. OS is up to date.
  This is repeatable on ubuntu 12.4(liveCD), 12.10, 13.4(liveCD).
  Sorry, I dont know how to find the affected package (and its version).

  thank you
