If you feel not the console for tracking some possible bugs, you could use
apport. This tool (only on Ubuntu) will help you in this task.You must
activate it followin g the documentation <https://wiki.ubuntu.com/Apport>.
Just a tip : type CTRL + Q for quit and valid after and restart you system.

I've done the necessary for the update of MLT and ask our interrogation.
