            Bug ID: 312238
           Summary: okular crash when load a malformed epub
    Classification: Unclassified
           Product: okular
           Version: 0.15.3
          Hardware: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: mercuriete at yahoo.es

Application: okular (0.15.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic i686
Distribution: Ubuntu 12.10

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

open a malformed epub.

1) rename some zipped file:        file.zip  to file.epub 
2) try to open this file with okular
3) okular exit with a segmentation fault signal

i think that is an error from libepub not from okular because in the backtrace
says this:

in _ocf_parse_container (ocf=0x9e26868) at
/build/buildd/ebook-tools-0.2.1/src/libepub/ocf.c:36

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
