Try to reproduce with symbols in the library, without them the traces are useless. Also what GPU are you using?
This is the inxi with a full detail of the PC. Tomorrow I'll try to reproduce the bug, now is really late here. I can add also that to use nouveau with KDE has been very hard, for me. I cannot use the compositor and no way to use the GPU like before (nvidia 304 driver, no longer supported). I'm using 4.17.5-1-zen #1 ZEN SMP PREEMPT, but the error is present with all the versions. I tried also to downgrade the glibc: no way. To reproduce with symbols have I to compile and install a custom version of the driver?

I believe kwin with a G71 (supported by the nv30 driver) works fairly poorly and crashes, as you've discovered. Someone else reported crashes a while back - I looked into them a bit, but ultimately didn't have time to properly resolve.
