Unfortunately the backtrace is incomplete and missing debug symbols that we need to figure out exactly what's going wrong:


#4  0x00007f38fda11d79 in KNotification::id() () from /usr/lib64/libKF5Notifications.so.5
#5  0x00007f38fda2e264 in ?? () from /usr/lib64/libKF5Notifications.so.5
#6  0x00007f38fda2e57f in ?? () from /usr/lib64/libKF5Notifications.so.5


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

Thanks!

I've installed the debug symbols, once I've managed to reproduce the issue I'll let you know. Annoyingly it's not happened again.
