            Bug ID: 392916
           Summary: Crash on okular being open for several days
           Product: okular
           Version: 0.26.1
          Platform: Debian stable
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: lfischer at staffmail.ed.ac.uk
  Target Milestone: ---

Application: okular (0.26.1)
KDE Platform Version: 4.14.26
Qt Version: 4.8.7
Operating System: Linux 4.14.0-0.bpo.3-amd64 x86_64
Distribution: Debian GNU/Linux 9.4 (stretch)

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

Okular was open with a dokument over night. This time several nights last time
just one night. 

Possibly "helping" condition was that I had a lot in memory  and parts of
okular where possibly swapped out.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
