Application: plasmashell (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.7-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

-- Information about the crash:
- What I was doing when the application crashed / unusual behavior I noticed:

1. I was experiencing internet connectivity problems (TCP connection attempts timing out, hostnames could not be resolved due to timeouts, etc)
2. Plasma hung for several minutes
3. After it recovered I logged out
4. It took Plasma a while to actually exit
5. On the next day I logged back in and found this crash report

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib64/libthread_db.so.1".
