Public bug reported:
Lubuntu 19.04 QA-test
I've been having trouble with pcmanfm-qt moving around the 2nd display
(other bug-reports) and thus been adjust position of the screens to see
if monitor-position effects the jumping-window-on-select of
device/folder/.. in pcmanfm-qt. On some of these display or monitor-
settings-adjustments the open windows for pcmanfm-qt has crashed/closed.
dmesg shows

The `dmesg` report snipped shows 3 crashes.
The significance is not great, the user (me) just re-opens pcmanfm-qt,
and no-one adjusts their screen-positions very often, and that is the
only time it crashed - so importance is low.
Possibly related (why I'm adjusting screen position) is 1804329m
1810079. 1812342 which are all problems I've had today with pcmanfm-qt
(causing me to change screen positioning & thus come across these
crashes).
