            Bug ID: 398334
           Summary: Okular crashes while highlighting PDF file
           Product: okular
           Version: unspecified
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: t.z.crawford at hotmail.com
  Target Milestone: ---

--Software Versions

Application: okular (1.5.1)
KDE Frameworks 5.49.0
Qt 5.11.1 (built against 5.11.1)
Operating System: 4.18.5-arch1-1-ARCH (Linux kernel 4.18.5)
Distribution: Arch Linux
Window manager: i3 (if that matters)
PDF Backend 0.6.5

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

An arbitrary highlightable pdf file was opened with okular (have tried opening
from both Okular>File>Open as well as from thunar and launching from zotero) 
The F6 button was pressed to open the review tool with the highlighter option
At least two separate sections of text were highlighted with the default yellow
highlighter. Doing this after highlighting only one section does not produce a
crash (at least not consistently).
CTRL+Z was pressed to undo the last highlighted text
Another section of text was then highlighted
Okular immediately crashes

- Custom settings of the application:

I have added a few extra colored highlighters to the review tool, but I can
make the crash occur using the default yellow highlighter only. Seems not
relevant to the bug.

-- Backtrace:

Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
