Bug 393512

I've broke my keyboard and a few days was forced to use context menu commands to copy/paste text in Konsole app instead of Ctrl+Shift+C/V hotkeys that I used to. And, unfortunately, I'm faced with annoying Konsole app crashes.

Launch Konsole, make sure it's not maximized. Launch some commands in it to get output that can't be displayed on single screen. Now you have vertical scroll bar in your window. Scroll it back to the top. Select some text with mouse then press right mouse button to get a context menu. The app will crash before context menu is displayed with SEGFAULT message.

System info:

$ konsole -v
konsole 17.07.70
$ uname -a
Linux t-laptop 4.13.0-22-generic #25-Ubuntu SMP Tue Dec 19 11:13:36 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
