It appears to be a bug in Okular itself.

Can you please do the following:
 * Install the debug packages for kdegraphics and qt for your distribution and post a backtrace with all the debug symbols (they might be called kdegraphics-dbg or something like that on Ubuntu)
 * Describe what you were doing (does it crash whenever you open the file or do you have to do something specific?)
 * Is it possible to attach a file that causes this crash to the report?

Thanks.

Unfortunately I can not install kdegraphics-dbg because of problems with 
dependencies in ubuntu. Sorry. Book attachment
 Regards

If you have dependency problems, they should be fixed :)

As for the rest, please answer what you were doing when the crash happened, and add the attachment using the "Add an attachment" link at the end of this report page.

Next time, please post the backtrace contents here instead of attaching it, as it makes it easier to look for duplicates.
