Qt Creator crashes when adding a newline (pressing Enter) between paranthesis if the last line of the source file is not visible.

Steps to reproduce:

1. Start Qt Creator
2. create new cpp source file
3. add newlines until the editor is filled
4. add some function
5. add an if statement in the function with opening paranthesis so Qt Creator will automatically add the closing one
6. scroll down until the if statement is in the last visible editor line
7. press enter with the cursor in between the paranthesis

To be extra sure see the attached screenshot.
