Comment 1 Friedrich W. H. Kossebau 2019-01-18 04:28:30 UTC

Thanks fro the report.

Seems the interesting point in the backtrace is

#16 0x00007f754034245c in __run_exit_handlers () at /usr/lib/libc.so.6

which is triggered from within /usr/lib/libQt5WaylandClient.so.5, possibly because some state was reached where QtWayland could not cope with and just calls exit on the whole process.

Possibly Plasma might need improvements in doing the clean-up here, so the exit does not escalate in a crash. But more important would be to prevent the exit call. Which would need to know what QtWayland paniced about, no idea how to debug that myself.

Nothing to do with the weather dataengine itself from what I can tell, so moving over to Plasma Generic bugs.
