[Pkg-kde-extras] Bug#755091: libkscreen1: Crash in configuration notification handling

[Ralf Jung]

Hi again,

> libkscreen triggers a crash in kded4 and/or plasma-desktop when I plug out

> laptop being re-enabled).
> I reported this upstream [1] and there is a patch there.
> 
> Please consider backporting that patch: While KDE has fairly good

> loose stuff I wrote into the notepad on my desktop that Plasma decided

For some reason, this got worse this morning: I am no longer able to use
kscreen appropriately. When I disable the internal laptop screen (e.g.,
to work on an external screen exclusively), kscreen crashes and the
previous configuration is restored. This makes kscreen completely unusable.

Please consider backporting the patch I mentioned in the initial report:
<https://projects.kde.org/projects/extragear/libs/libkscreen/repository/revisions/891fea508e1d1157ce6cd8ddc6005fc4b8f563fd/diff>

Kind regards
Ralf
