Confirmed. 

AutoMask on the track header-> click analyze -> crash. 

Opened issue https://invent.kde.org/kde/kdenlive/issues/192
Comment 2 emohr 2019-05-20 16:13:54 UTC 
Solved. https://invent.kde.org/kde/kdenlive/commit/50e1cb6304294eaa871a53acc776d1392bc5771c

Automask cannot work on tracks so the button analyze is disabled if effect is applied on a track.
