Seems this is related to a regression introduced by this bugfix to Qt: https://bugreports.qt.io/browse/QTBUG-21739
** Package changed: ubuntu-ui-toolkit (Ubuntu) => qtcreator (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1452956 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.
