            Bug ID: 395684
           Summary: Segfault after closing "file not found" dialog after
                    reboot
           Product: okular
           Version: 1.4.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: me at dennis-irrgang.com
  Target Milestone: ---

Application: okular (1.4.2)

Qt Version: 5.11.0
Frameworks Version: 5.46.0
Operating System: Linux 4.17.1-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I zypper dup'd my system and did a reboot. A file was not found (I had moved it
to a different folder after opening the file and forgot about that) after
booting and KDE recreated the session. I closed the dialog and that's when
Okular crashed.

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