Unfortunately, the backtrace lacks debugging information that would indicate what data is involved at the time of the crash. Please report the crash using apport, see https://wiki.ubuntu.com/Apport for details.
Moreover, it indicates that the mlt interacts in a strange way. I'm therefore reassinging this issue to mlt. ** Package changed: libav (Ubuntu) => mlt (Ubuntu) ** Changed in: mlt (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libav in Ubuntu. https://bugs.launchpad.net/bugs/1176082 Title: Segmentation fault in libavformat when frequently pausing and unpausing video playback in openshot Status in “mlt” package in Ubuntu: Incomplete Bug description: When editing a video in openshot, pausing, moving clips around in several tracks and then unpausing will cause it to suddenly crash. With a few paralell tracks in the project, this happens frequently, often after just a couple of secons of use. Attaching gdb it seems the problem lies in libavformat which carches a segmentation fault, backtrace attached.
