This is actually an issue with apport-retrace and how it manages its
sandbox directory.  I'll mark this as a duplicate of the new bug I've
reported about apport.

Title:
  issues debugging program threads on 12.04

Status in “gdb” package in Ubuntu:
  Incomplete

Bug description:
  The Ubuntu Error Tracker is still experiencing some failures when
  trying to retrace armhf crashes from Utopic.  The retracers for the
  Error Tracker are running 12.04 (with a backported version of gdb from
  Trusty) and I've attempted to manually retrace a failing .crash file
  using apport-retrace.  Here is the output from gdb with 'set debug
  libthread-db 1' in my .gdbinit file.
