--- Comment #3 from Michal <michal.kl...@gmail.com> ---
Same problem, disabling GPU acceleration in KDENLIVE solved the problem
instantly.  Using gtx 770 with 375.26 drivers on KDE NEON.

Backtrace of the crash I experienced:

Application: Kdenlive (kdenlive), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
