Application: plasmashell (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.4.1-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:

1. The monitor went to standby.
2. A while later (ranging from a few seconds to several hours) I turned it on again by moving the mouse.
3. I find Plasma, KWin, ksmserver, yakuake and others crashed.

This is reproducible every time and has happened several times already.

This is a duplicate of bug #357085, but due to DrKonqi bug #355807, I cannot conveniently attach this information there.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
