Given that it's NVIDIA hardware we can assume it's the same bug as always.

--- Comment #4 from Christian Höne  ---
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.

I don't know if this is sufficient. I installed kwin5-debuginfo.

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.
