@Zoubidoo I used bt and the answer was: 0xb6e669e8 in mlt_event_unblock () from /usr/local/lib/libmlt.so.2
I used pystack macro, but after a long time (30 min) I had no answer: so I quit. In alternative I launched: python -dv /usr/bin/openshot and the result is in the attachment. I hope this will be useful. I didn't understand why pystack/pystackv was silent. Suggest me some other option.
