Bug 386931

Application: kdeinit5 (16.12.3)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.9.56-desktop-1.mga6 x86_64
Distribution: "Mageia 6"

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

Browsing pdf in Envice then closed envice and dolphin  crashed. Sometimes closing dolphin will result in dolphin crashed bug coming up. kdeinit has crashed more rarely.

The crash can be reproduced sometimes.

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