Avidemux3-qt5 crashes EVERY time

Hello
On my previous system (OpenSuse 13.2) I had Avidemux working fine.
Since new installation of Leap 42.1 I have problem with Avidemux. I use it to ‘burn’ subtitles into videos.

The problem is such:
Avidemux crashes every time I use. I load video, add subtitles and for several minutes it does its work. But then, usually around 30% it crashes.
I paste output from console.
