            Bug ID: 338061
           Summary: Okular modify a PDF page when highlight and crashed
                    when it's removed
           Product: okular
           Version: 0.19.3
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: apcomptec at gmail.com

Application: okular (0.19.3)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.15.7-200.fc20.i686 i686
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
- What I was doing when the application crashed: 
1. Open a PDF eBook
2. Highlight a pair of lines (accessed pressing F6)
3. Occured and odd behaviour: All content in the page where I highlight simply
dissapeared and the blue color of the highlight (because I'm using the 'Inverse
colors' from 'Accessibilty') is the only showed (excluding their text). The
content in other pages was also modified (only pictures can be viewed, no text)
4. Delete the highlight
5. Crash occur

When I reopen the eBook, I see the same as before deleting the highlight.

The crash can be reproduced every time.

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