Bug description:
  [Impact]

  An invalid line of code would occasionally cause Unity to crash.

  [Test Case]

  (1) Download and run the attached Python script test-1374942 to create a candidate application.
  (2) Press the close button and wait for the Force Quit dialog to come up.
  (3) Choose the "Force Quit" button.

  The desktop shell should not crash.

  [Regression Potential]

  The fix for this bug involves converting an integer into a string and
  appending it to an error message instead of adding the integer value
  to the address of the error message.  There is unlikely to be a
  regression from this.

  [Other Info]

  The fix for Ubuntu 14.04 LTS was cherry picked from the Ubuntu "Vivid
  Vervet" dev release where it has been under daily use for some time
  without apparent regressioon.
