closing this rather old issue. sorry for not addressing this earlier.
Please could you recheck with the recent 14.04 LTS or 14.10 releases and

Title:
  gdb hangs eternally when opening with upowerd core file

Status in “gdb” package in Ubuntu:
  Invalid

Bug description:
  Today we noticed that the apport-retracers were hanging indefinitely
  with gdb spinning with 100% CPU power on retracing bug 1019781.

  I can reproduce this manually with the attached upowerd binary (which
  is just the one from the Ubuntu 12.04 i386 upower package) and
  attached core dump (which is from bug 1019781) even in an environment
  where none of the actually used libraries are being installed. It
  happens in the reconstructed environment from the crash as well, and
  it behaves equally in precise and quantal with their respective gdb
  versions:

  From here it's spinning eternally without further output. stracing
  gives a neverending stream of

  (with exactly the same numbers).
