It can be reproduced that way, but also not every time (but it is pretty
frequent). No matter how I open Konsole (using global shortcut, from kickstart,
or from dolphin's Shift+F4), sometimes, but not always, either this bug or 100%
core CPU bug is triggered. This only happens on my PC with NVidia hardware.

Also, when the Konsole hogs 100% core CPU, it can be closed instantly by
issuing SIGINT (no need for SIGKILL) to the offending process.
