           Summary: Random crash of Okular in background
           Product: okular
           Version: 1.4.1
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: salvatorebaldino at gmail.com
  Target Milestone: ---

Application: okular (1.4.1)

Qt Version: 5.11.0
Frameworks Version: 5.46.0
Operating System: Linux 4.16.11-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Okular seems to crash randomly even while I am not using it but I just have
some okular documents (low number, up to 5 documents) in background. The
crashes are rare, and I am not able to reproduce them.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Okular (okular), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
