-- Information about the crash:
Steps to reproduce:

Open Konsole and start vim with the file /usr/share/X11/locale/en_US.UTF-8/Compose

Now press and hold the PageDown button, so that vim scrolls down the text. If vim reached the end of the file and Konsole didn't crash yet, press and hold the PageUp button.

At some point Konsole will crash with the backtrace below

 -- Backtrace:
