What may or may not be related is that tiling is also visually broken (see

I can reproduce it with kwin_wayland --exit-with-session "konsole -platform
wayland"

The weird thing is that I've seen multiple different backtraces for the
seemingly same crash. This one seems to appear most often:

Trace doesn't really make sense.

We're still inside the InternalClient constructor, a crash whilst emitting our
own signal implies we've somehow deleted "this" from inside here. 

I can't reproduce, Nico could you try nested and with valgrind? 

Also a clean build
