As zoominee did, I reported a similar bug on KDE forum: <a href="https://bugs.kde.org/show_bug.cgi?id=353292">https://bugs.kde.org/show_bug.cgi?id=353292</a>. There, you can access the stacktrace (on an Archlinux system). You also have the dmesg messages.

Please see the attachment. I can also add that it makes the plasmashell application hangs for a while, with 100%CPU usage. After some time, the system is responsive again, with some glitches in the interface (meaning, some icons disappearing or wrongly displayed for instance. Once, it made the file explorer dolphin crash). It has been identified by a problem with nouveau (I refer you to the <a href="show_bug.cgi?id=92077#c4">comment 4</a> of the ticket, that gives better understanding of the problem): <a href="https://bugs.kde.org/show_bug.cgi?id=353292#c4">https://bugs.kde.org/show_bug.cgi?id=353292#c4</a> Thank you for your time! And keep the good work going!
