I got a crash on the activity banner (where the clock is and all that) when closing down Firefox windows. Automatic crash report was generated but the system didn't want to send it. So I'm doing it manually. Debug from the crash assistant attached with this bug report. Reproducible: Didn't try Steps to Reproduce: 1. Close down Firefox windows. 2. ??? 3. ??? Actual Results: The banner with the clock and open windows suddenly crashes. Expected Results: It should not have crashed.

Created attachment 102605 [details] crash report of plasmashell crash when closing down active window I had a new crash in plasmashell. I don't know why this keeps happening.
Please install debug symbol packages for plasma-workspace and Qt, then upload the backtrace when it crashes again -- the current backtrace lacks too much information to be useful.
This bug continues to happen. Here is the latest crash. As before, I'm closing windows when the crash happens. I have added debug flags to the compile process. Next time the KDE is updated they are going to be added to the new version. I'm running KDE plasma 5.8.5. ----- Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
