Konsole terminal crashes after changing monitor (xrandr)

[Vaclav Petras]

On Lubuntu 15.04, Konsole (lxsession-default terminal) and perhaps other Qt-based applications (noticed with QtCreator) crash with segmentation fault after changing monitor settings for example from:

    xrandr --output VGA1 --auto --output LVDS1 --off --output HDMI1 --off

to:

    xrandr --output HDMI1 --auto --output LVDS1 --off --output VGA1 --off

You can see them after the change for a while but then they fail. It happens every time I change settings. No problem with application like Firefox, lxterminal, Geany, Kile, PCManFM or Leafpad.

Obviously, it terminates all programs running in the terminals which messes up whatever one is working on.
