Comment 1 weltqgel 2017-11-01 21:27:27 UTC

I can reproduce the issue.
Apparently nothing to do with Redshift.
Crash occurs when using a Hue Plasmoid activity that triggers multiple lights at once. (I will try to attach a screenshot of the configuration window of that activity)

Screenshot

If someone points me to the directory where the config files are stored for that Plasmoid, I will attach the config files as well

If you can install debug symbols for KIO widgets that would be great.

I don't understand why we're in widget code here.

Also this trace shows we're copying a file? Any ideas.

Debug symbols: It looks like there are no debug symbol packages available for Manjaro (Arch-derivative). Is there anything else I could try?

Comment 5 weltqgel 2017-11-04 16:31:44 UTC

I can add that upon first time triggering the "Wohnzimmer alle aus" command plasma does not crash. Only when triggering it a second time (hence asking to switch out all lights a second time), the crash occurs. It does not matter if the there was anything to switch out by the first command.

Comment 11 weltqgel 2018-02-01 16:57:01 UTC

Created attachment 110287 [details]
another backtrace

I think I found something out: when I was editing one of the lights to not only change state (on/of), but to also change color temperature, I accidentally defined the color change for a different group of lights instead of the one I wanted to change. Some members of this group could not respond to the command (since they are permanently switched off).

That is, it seems that the error handling (from non-responding lamps) is the culprit, not the mere fact that more than one command is sent out.

Comment 12 weltqgel 2018-02-02 16:45:29 UTC

Forget comment #11, Plasma crashes also when the Hue widget is asked to perform two actions on one (available) lamp.

Comment 13 weltqgel 2018-02-02 16:56:01 UTC

Finally, the point is, whenever two commands get sent out (command 1: change state; command 2 change colour OR command 1: change group 1 and command 2: change group 2), Plasma crashes. 

If I combine the two commands in one (changing state and colour OR greating a new group with all lamps previously in groups 1 and 2) all is fine.

So the problem lies in the paralellization of commands.

Maybe that info helps.
