I tried with deactivating the addressbook sources, that didn't help. This is a 
clean install, I only just bought this thinkpad :)

But I tried forcing kmail to render in xwayland, and the completion worked 
without crashing.
--> I can only conclude that the completion suggestions are drawn incorrectly 
in wayland, and/or make assumptions that don't hold outside of kwin.

It's hard to debug this without stacktrace though, I understand that...
At least it should be easy to reproduce: Start kmail in sway, complete some 
email address. I assume that a similar issue should occur in other wayland 
compositors that aren't kwin.

Cheers,
