Description Tristan 2020-08-17 12:44:38 UTC 
Hi there! I use KDE neon Unstable for the latest features, but this time when the updates were finished, some weird behavior was happening so I decided to reboot the system. Even weirder behavior was happening, and looking in dmesg I found that sddm-greeter got segmentation fault'ed by libQt5Core.so.5.14.2 and plasmashell by libKF5Service.so.5.74.0.

STEPS TO REPRODUCE
1. Update packages to the lastest version
2. Reboot the system

OBSERVED RESULT
1. I noticed the splash screen after login taking over a minute (this usually takes like 10s max)
2. Wallpaper is not showing
3. Latte dock, krunner, widget etc. are not working
4. Crash reports can't be collected

EXPECTED RESULT
The OS to work properly (I'm sorry :))

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon Unstable 
KDE Plasma Version: 5.19.80
KDE Frameworks Version: 5.74.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION
The following is the important part of the dmesg output:

I have updated my neon unsable a few hours ago and since then plasmashell does not load anymore. I only see a black screen with cursor after login.
