Try to reproduce with symbols in the library, without them the traces are
useless. Also what GPU are you using?

--- Comment #2 from Frank <fpedersoli at kisantechnology.com> ---
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?

--- Comment #3 from Ilia Mirkin <imirkin at alum.mit.edu> ---
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.
