bug

Hm as I see here bug was fixed in 5.9.4 https://cgit.kde.org/plasma-workspace.git/commit/?h=Plasma/5.9&id=bcb6b86d3ab8bd196877473af343b72c53e4f932 but I reported it at this version!

Make this reopened.

Yeah sorry the (hopefully proper) patch is still pending, will finalize it tomorrow (so it will be in 5.9.5)

*** Bug 378894 has been marked as a duplicate of this bug. ***

Git commit 58206408a35a0900b5678231b7aaf490b2a3ec10 by Kai Uwe Broulik.
Committed on 18/04/2017 at 21:46.
Pushed by broulik into branch 'Plasma/5.8'.

When deleting the panel the notifications applet is in, the containment is being destroyed but the corona
is still there and rightfully emits availableScreenRectChanged.
This will cause us to crash when we try to access the no-longer existing containment.

Git commit 6ffe068b80143ba92cae6eaddf1bcd42c5ff4bed by Marco Martin.
Committed on 09/06/2017 at 14:16.
Pushed by mart into branch 'master'.

generate the old key before updating enabledborders

Summary:
sometimes a frame changed enabled borders causing a dangling
pointer in s_sharedFrames, since oldkey was generated
with the new enabled borders, it generated a key not present
in the hash, tryed to remove it and left the one associated
with the old key in the hash.
if the need to reuse a frame with that key ever arised again,
we had a crash

Test Plan:
couldn't reproduce the crash neither with or without patch,
with the patch, if i put debug in every place a framedata is removed,
searching if the key is in the hash before removing it, now
it's always true, before sometimes it was false

This crash is still reproducable in 5.8.7 and 5.10.3.

See also https://bugzilla.opensuse.org/show_bug.cgi?id=1046500

The crash happens reliable if I actively close the appearing notification (about the panel having been removed) by clicking on the 'X'.
If I wait for it to timeout, Plasma doesn't crash (immediately at least, it seems likely to crash sooner or later afterwards anyway).

[Notifications] Check for corona to avoid crash

My previous attempt only fixed the case when notifications were directly in a panel.
Now it also no longer crashes when removing a panel that has a System Tray with the
notifications applet in it.
FIXED-IN: 5.8.8
