--- Comment #7 from farid <snd.noise at gmail.com> ---
Hmmmm, on my notebook and a crash happens while on the desktop it doesn't. This
*could* be since my desktop has an nvidia card while the notebook doesn't have
a dedicated graphics card. Maybe have kdenlive detect if there is a gpu before
starting otherwise disable movit support.

Here is the backtrace:
