Bug 358373

Application: kdeinit5 ()

Qt Version: 5.5.1
Operating System: Linux 4.1.6-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

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

I resumed my laptop from s2ram. Then I plugged in my external monitor. NO crash! I started to work.
Often, my laptop goes to sleep again when I close the laptop lid (Which it should not do when there is an external monitor plugged in... but this is another story) . It did not go to sleep this time.

BUT after a few minutes this crash happend AND my laptop immediately went into sleep mode. After resuming I am now writing this bugreport.

-- Backtrace:
Application: kdeinit5 (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
