Bug 394707

Application: okular (1.4.1)

Qt Version: 5.10.0
Frameworks Version: 5.46.0
Operating System: Linux 4.16.11-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

KDE was booting and Okular did not find some files it was showing in the previous session because they had been moved to another directory. While the dialog box with the name of the file was showing, I tried to open the file with another instance of Okular, and then this crash has happened. Notice that the new instance of okular did not crash, only the instance that showed the dialog box.

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
