    Description

      When editing QML or JavaScript files the QtCreator crashes if you try to input " character to end of the line while cursor line is not visible. Text Editor Completion for automatically inserting matching characters needs to enabled.

      To reproduce:

      1. Open up/create a QML/JS file that is longer than the editor view.
      2. Move mouse cursor to end of line somewhere at the top of the file (for example end of line 2)
      3. Scroll down with mouse while keeping the cursor position at the top (line 2)
      4. Once line where the cursor is located (line 2) is no longer visible you have scrolled enough
      5. Insert " character
      6. Crash
