            Bug ID: 323721
           Summary: Okular crashes on corrupted pdf
    Classification: Unclassified
           Product: okular
           Version: 0.16.5
          Platform: Debian unstable
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: f.presel at alice.it

Application: okular (0.16.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.5
Operating System: Linux 3.10.5-desktop-f x86_64
Distribution: SolydK

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

I tried to open a file which had the extension .pdf but whose content was
actually only made of null characters (0x00). The okular window initially
appeared; then, instead of displaying the window "this file is not valid" (as
it used to), it just crashed

The crash can be reproduced every time.

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