Thanks for the additional info. I installed ubuntu 16.04 and sure enough got the segfault on exiting jqt. I then copied over my own build of jqt (using Qt 5.5 instead of 5.3 as distributed) and no longer got the segfaults. Nor have I seen them yet on my Linux Mint 18 cinnamon, even with the distributed jqt.
I'll try to track this down, but since it only occurs on exit, I believe it should not affect the normal use of jqt. On Mint cinnamon and Ubuntu 16.04 nautilus (if set in the nautilus preferences), clicking an executable shell script gives a prompt with options which include "run in terminal" and "run". If "run in terminal" is selected, both jconsole and jqt show up. If "run" is selected, only jqt shows up, since jconsole requires a terminal. Is there something like this prompt or preference in the mate file manager? It sounds like it is set to run shell scripts without a terminal.
