Hi,
I've just upgraded my MLT to the most recent git master, which is around
10 days old. Now Kdenlive crashes repeatedly after a few positioning
actions in the timeline, always in frei0r-1/multiply.so. As I'm not sure
if MLT is at stake, or some other unnoticed updated sneaked in, I'm
asking here for help first before pointing fingers.
System is Kubuntu 16.04 LTS with backports ppa enable, all updates
installed as of today.
fei0r-plugins is 1.5+git201604011602-0xenial1; maintainer is Vincent ;)
MLT is compiled from git master as of today.
Kdenlive is compiled from git Applications/16.08 as of today.
Render threads is set to 1.
This is the backtrace, any ideas...? Best regards, Harald
