            Bug ID: 395029
           Summary: Segmentation fault when changing opened PDF
           Product: okular
           Version: 0.25.0
          Platform: Mint (Ubuntu based)
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: krzmbrzl at gmail.com
  Target Milestone: ---

I am creating a document using LaTeX and while doing so I like having the
created PDf opend in Okular in order to properly inspect it.
However after recompiling the LaTeX source and thus recreating the PDf file
Okular tends to crash. This behaviour is rather new (I experienced it in the
last couple of weeks but before everything worked well) and it doesn't occur
always but pretty often.

I am experiencing this bug on Linux Mint 18.3 and here's the output of okular
--version:
Qt: 4.8.7
KDE Development Platform: 4.14.22
Okular: 0.25.0

And this is the backtrace as created by the KDE bug-report manager:
Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
