Plasma Desktop backtrace

Version:           unspecified (using KDE 4.8.0) 
OS:                Linux

I upgraded systemd from 37-4 to 42-1 and Plasma Desktop crashes after login.

Reproducible: Always

Steps to Reproduce:
Run Fedora Rawhide with systemd 37-4.
Update to systemd 42-1.
Desktop fails to load after login.


Expected Results:  
Desktop still loads after systemd update.

Attached generated backtrace:
 
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
