Comment 1 Marco Martin 2017-03-09 16:42:38 UTC

line numbers don't seem to correspond exactly with the 5.8.3 tag, btw, the crash is probably at line 1792 if (m_desktopViewforId.value(id)->containment() == containment && containment->activity() == m_activityController->currentActivity()) {

like screenForContainment was called before the deleted desktopview was removed fro mthe pool

Comment 2 Marco Martin 2017-03-09 17:00:00 UTC

in the notifications applet, 
connect(KWindowSystem::self(), &KWindowSystem::workAreaChanged,
            this, &NotificationsApplet::onScreenChanges);

seems to trigger onScreenChanges, then containment()->corona()->availableScreenRect(containment()->screen()); in the middle of the way between view deletion and removal from the list

Comment 4 Marco Martin 2017-03-10 11:16:48 UTC

Git commit bcb6b86d3ab8bd196877473af343b72c53e4f932 by Marco Martin.
Committed on 10/03/2017 at 11:16.
Pushed by mart into branch 'Plasma/5.8'.

try proper order of corona()->availableScreenRect()

Summary:
connect to Plasma::Corona::availableScreenRectChanged
instead of using kscreen, this way we should be more sure
that signal is emitted when it's safe to call
corona()->availableScreenRect() as the change of rect
may happen after a screen removal, so may mean
accessing a desktop view while being deleted

Test Plan:
notifications still pop up in the proper place,
couldn't reproduce the crash neither before nor after tough
