Same issue here--but only with one particular audio CD.  DVDs and other
audio CDs work fine.  I have Ubuntu 12.04 kernel 3.5.0-47-generic.  The
same CD causes the same problem on another laptop with a different CD
drive (same Ubuntu kernel).  Syslog has this line for each time I insert
the CD:

Mar 29 16:13:37 system kernel: [151273.462458] pool[16054]: segfault at
7fe6b2d5570e ip 00007fe6b21ea3b1 sp 00007fe6b0921eb0 error 4 in
libc-2.15.so[7fe6b219f000+1b5000]

I cannot test another kernel at this time.

Title:
  Unable to mount audio disc - Message did not receive a reply (timeout
  by message bus)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have an Asus external slim USB optical drive and when I insert an
  Audio CD, Unity pops up a message with the text in the summary:
  "Unable to mount audio disc - Message did not receive a reply (timeout
  by message bus)".  I'm able to open VLC and successfully play the
  audio disc, so I don't think it's a hardware issue.  I've tried
  checking the box marked "Never prompt or start programs on media
  insertion" in the System Settings in the Details -> Removable media
  section with no change in behavior.

  Here is some hopefully relevant info:
