Title:
  Stale lock file causes QtCreator to freeze when starting

Status in qtcreator package in Ubuntu:
  New

Bug description:
  I was debugging why my ubuntu-sdk instance would not start up (it
  instead freezes indefinitely) when I noticed a stale lock file under
  ~/.config. I removed this file and the IDE started.

  To reproduce:

  1. Execute the following from the terminal: touch ~/.config/QtProject/QtCreator.ini.lock
  2. Start qtcreator or ubuntu-sdk.

  Expected results: The IDE starts as expected
  Actual results: The IDE hangs indefinitely

  Any sane IDE should be able to handle stale lock files--such a thing
  should not prevent the application from starting.
