Comment 1 Martin Flöser 2017-05-05 17:08:21 UTC
Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install the debug packages and attach a new backtrace. Without the debug symbols we do not see where it crashes.
Comment 2 Christian Höne 2017-05-06 20:27:45 UTC
I don't know if this is sufficient. I installed kwin5-debuginfo.

Comment 3 Christoph Feck 2017-05-09 09:44:40 UTC
Thanks for the update.
Comment 4 Christian Höne 2017-05-09 10:32:23 UTC
additional info:

- crash time is not necessarily at where you unlock.
- hard to say how long monitor has to be off, but it is about 90% probability that this crash happens if monitor is off for more than 30min, if you turn off monitor only for a short time it doesn't occur.
- crash happens not only on one machine. what is in common: openSUSE 42.2, nvidia graphics card with proprietary driver and a monitor connected via display port.
