Application: plasmashell (5.8.4) Qt Version: 5.7.1 Frameworks Version: 5.29.0 Operating System: Linux 4.4.39-1-MANJARO x86_64 Distribution: "Manjaro Linux" -- Information about the crash: - What I was doing when the application crashed: Nothing special: I started my laptop, logged in. Plasma loaded. After it loaded, the crash-icon was visible in the system tray. - Unusual behavior I noticed: Loading took quite long. That is: longer than usual. This happens me about once in two times I log in, since the last update. If I remember correctly, that update consisted of KDE frameworks 5.28 to 5.29, KDE app 16.08 to 16.12, and some other updates I forgot. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

Created attachment 103015 [details] last update This file contains the pacman log of the last update. After it completed and a manual reboot, I got the plasma crashes.
For the record: I tried it again: * Shut down my laptop with the shut down entry in krunner * Waited till it was shut down * Pressed power-on button * Pressed enter when grub shows * Waited till sddm showed up * Entered my password * Waited till plasma was loaded * Discovered the crash-icon in the system tray

Update 5.8.5 of plasma seems to fix it.
(In reply to thalesii from comment #4) > Update 5.8.5 of plasma seems to fix it. That is, right after the update and a reboot, it didn't crash. Next time after, it did.

I think so, because at the last crash, firefox auto-started at login.
