Public bug reported: KDE5 won't start for me today, and there are segfaults in dmesg (XFCE is running fine):

A couple of weeks ago the KDE panel stopped appearing/but I didn't have time to report it. As of today the desktop doesn't start and I'm returned to th display manager. I've done an update today and it still doesn't play ball. I tried wiping .kde/cache* and it didn't help.
