I suggest taking this upstream to https://bugs.kde.org, cause it really sounds 
like an upstream bug.

Especially when you can create a ~/.local/share/kscreen with contents that 
make a desktop session crash on login, that may help – of course it may only 
crash with exactly the three monitors you have connected. So please also 
install the necessary -dbg packages and try to create a backtrace.

You may even report upstream by using DrKonqi.

I have seen some issues kscreen but no crash on login yet. Using the laptop 
and one external display.

Thanks,
