Title:
  Ubuntu Software Center shows empty error message when aptitude is
  running

Status in “aptdaemon” package in Ubuntu:
  Fix Committed

Bug description:
  Binary package hint: software-center

  When having aptitude open in a terminal (sudo aptitude) and trying to
  remove a package in Ubuntu Software Center, it first fails with a
  empty error message, followed by a message that the program aptd
  closed unexpectedly. I'm guessing the the Software center isn't
  checking whether the database is locked by a different package manager
  or doesn't handle this case correctly.

  Sometimes this message appears along with it: An unhandles error occured.
  Details: Traceback (most recent call last):
    File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 166, in _process_transaction
