    Description

      I just had a segfault when I started Qt Creator opened a project and quickly went to Right Click->Refactor->...

      Then it crashed with the following backtrace. It isn't easy to reproduce but maybe there's something obvious in the code? At the very least you can add a null check. Must be this line:
