[Bug 1170421] Re: Live session shutdown "hangs" (not showing "Please remove media ..." message)

[Nightfall]

Still testing with Kubuntu raring daily iso of 2013-04-19 running as
live system:

No message on shutdown on Samsung R55 when "16bit debug override" is
enabled in /lib/plymouth/themes/kubuntu-logo/kubuntu-logo.script
(uncommented line // Window.GetBitsPerPixel = fun() { return 4; };)
(tried once).

No message on shutdown on Samsung NC10 with non-modified theme files
(using default kubuntu-logo theme with glowing "Kubuntu" logo being
shown) (tried once).

Title:
  Live session shutdown "hangs" (not showing "Please remove media ..."
  message)

Status in “casper” package in Ubuntu:
  Confirmed
Status in “plymouth” package in Ubuntu:
  Confirmed

Bug description:
  Testing with Kubuntu raring daily iso of 2013-04-18 running as live
  system from a USB flash drive (on a Samsung R55 laptop).

  During shutdown, the system "hangs"; when a key (e.g. Return) gets pressed, shutdown completes.
  Probably the "Please remove installation media ..." message (which prompts the user to press Enter to complete shutdown) is missing.

  This has been the case with (at least) 2013-04-12's Kubuntu raring
  daily iso, too.

  Could also be a problem with Plymouth/Kubuntu's plymouth theme...
  Plymouth splash is the logo one (graphical "Kubuntu" logo with glow is shown).
  Version: plymouth-theme-kubuntu-logo: 13.04ubuntu9

  This bug might be similar to/the same as bug #966480 (which concerns
  shutdown after installation).
