            Bug ID: 296587
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: okular-devel at kde.org
           Summary: Okular crashed on print preview of document with
                    Chinese characters and forms
    Classification: Unclassified
                OS: Linux
          Reporter: dap56 at cornell.edu
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: okular

Application: okular (0.13.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

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

I had filled out this PDF form (
http://www.visaexpress.net/china/china-visa-application-form.pdf ), saved a
copy, opened the copy, and selected print preview. The print preview window
appeared with 4 blank pages (loading the print preview, I assume). I scrolled
down while waiting for the print preview content to load, but after a few
seconds Okular crashed instead. Performing the same actions caused the same
behavior a second time.

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
