Description Daniel Perelman 2012-03-22 21:57:24 UTC 
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

Comment 1 Albert Astals Cid 2012-03-22 23:16:27 UTC 
It is crashing inside freetype when libghostscript calls it, not something directly related to Okular code itself. I can't reproduce the crash in my Ubuntu 12.04 installation so I guess the crash has been fixed somewhere in the upgrades of libgs or libfreetype versus the versions in your Ubuntu 11.10.

If you update to Ubuntu 12.04 (or anything containging versions of freetype >= 2.4.8 and libgs >= 9.05) and it still crashes please reopen the bug.

Thanks for caring about Okular :-)
Comment 2 Bernd Oliver Sünderhauf 2012-11-04 15:30:26 UTC 
Still more or less reproducible on Kubuntu 12.10 with the newest stack of:
 okular: 0.15.2
 libspectre: 0.2.7
 ghostscript: 9.06
 libfreetype6: 2.4.10
Upon preview, it's just that Okular hangs forever and freezes for me, rather than crashing.
Please reopen.
Comment 3 Bernd Oliver Sünderhauf 2012-11-04 16:20:15 UTC 
See also the test case of Bug #309537, which also freezes Okular upon preview.
Comment 4 Albert Astals Cid 2012-11-05 18:51:53 UTC 
It doesn't hang forever. It's just that spectre is unable to render the PS preview, nothing we can do about that so not reopening the bug.
