Comment 1 Friedrich W. H. Kossebau 2018-04-19 19:44:43 UTC

Given the backtrace currently showing to crash somewhere on destructing the weather dataengine:

Do you have an instance of the default Plasma weather applet running?
If so, please remove the applet intance and retry. Does it still crash?

Comment 2 Patrick Silva 2018-04-19 20:16:45 UTC

Yes, I have weather applet enabled in my system tray.
Crash is still reproducible even after I disable it and restart Wayland session.

Comment 3 Friedrich W. H. Kossebau 2018-04-19 20:29:18 UTC

Thanks. Does it still have the same backtrace, so crash somewhere in WeatherEngine::~WeatherEngine()? If not, please paste the new backtrace you get.

Comment 4 Friedrich W. H. Kossebau 2018-05-16 15:13:45 UTC

Looking again at the backtrace, I now spotted that in the middle of the call stack there is some
    QtWaylandClient::QWaylandDisplay::exitWithError()
which does nothing else than calling
    ::exit(1);

on which then some exit handlers are invoked by whatever, which seem to not properly shutdown things.
At least I can see nothing wrong in the weatherdataengine code itself which would explain why it then crashes in ~DataEngineConsumer().

So for the given crash itself I suspect something wrong in memory management code of the Plasma libs on such a forced deconstruction, thus moving over to that product.

Comment 5 Patrick Silva 2018-06-12 20:35:32 UTC

Cannot reproduce the crash on Arch Linux running plasma 5.13 + frameworks 5.47 under Wayland.

Comment 6 Patrick Silva 2018-06-14 01:14:57 UTC

also cannot reproduce on neon dev unstable after upgrade to qt 5.11.
