Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #5  0x00007f7a37effbd7 in ?? () from /usr/lib64/qt5/plugins/plasma/applets/org.kde.plasma.private.systemtray.so
> #6  0x00007f7a37effe39 in ?? () from /usr/lib64/qt5/plugins/plasma/applets/org.kde.plasma.private.systemtray.so

Could you please install debug symbols for Plasma, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
