Reproducible: Sometimes
Comment 1 RJ 2016-04-26 16:34:33 UTC 
Created attachment 98618 [details]
steps for reproduce

1. Input city or town
2. Search
3. Choose the city and click on Apply and as fast as you can click on all three tabs (Weather station... etc)

Crash will appear 2 times per 10 tries if not just reopen weather preference window and try again.
Comment 2 RJ 2016-11-04 07:18:02 UTC 
If one can't reproduce the bug just close Weather Settings window and open it again.

Qt 5.7.0
Plasma 5.8.1
Frameworks 5.27


Bug is still here.
Comment 3 Friedrich W. H. Kossebau 2016-11-04 08:57:28 UTC 
Thanks for the detailed report. I can reproduce the bug here.

No idea though where to start to find why things fail here :/ I need to take a course in QML debugging first.

For reference, my versions are:
Qt: 5.7.0
KDE Frameworks: 5.27.0
Plasma: 5.8.2
openSUSE Tumbleweed

When running "plasmawindowed org.kde.plasma.weather" in gdb, this is the stacktrace I get, so seems the same (when assuming more symbols optimized out in my packages).

Comment 4 Friedrich W. H. Kossebau 2018-05-12 07:54:41 UTC 
*** Bug 372930 has been marked as a duplicate of this bug. ***
Comment 5 Friedrich W. H. Kossebau 2018-05-12 08:06:18 UTC 
Given that the root of the crash reported here could be never identified in the weather applet sources, and that there have been no reports with more recent versions of both Qt and Plasma Framework, also could I no longer reproduce myself this crash with those newer versions, I for now assume the cause of this crash has been either in Qt or Plasma in older versions of those.

So closing this bug for now as resolved for some bug list housekeeping.

Please reopen if you still can reproduce this crash.
