-- Information about the crash:
systemctl start docker.service -> plasmashell crash.

In fact it seems a solid issue, according to the backtrace.
solid and Qt5 packages for Arch Linux were rebuilt, to get the debug symbols.

The crash can be reproduced sometimes.

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