Comment 1 Friedrich W. H. Kossebau 2017-10-10 15:24:22 UTC

Thanks for the report. Though this seems to be not about the weather widget from kdeplasma-addons, but the one from https://store.kde.org/p/998917/ (based on the version number you gave, which matches the one used there).

Sadly cannot tell instantly where that project takes bug reports, you will have to find out.

Comment 2 David Edmundson 2017-10-10 16:42:17 UTC

We do have an open report on the QMetaObject::cast it's from internals in QtQuickControls
