Title:
  bpython: crash after a few seconds related to apparmor

Status in bpython package in Ubuntu:
  New

Bug description:
  Something goes wrong in the import completion code, as it tries to
  open an apparmor-related sysfs file. The crash appears a few seconds
  after launching bpython. Seems fixed upstream.
