Thread Stacktrace

If I open a with Openoffice created and encrypted PDF in Evince it crashes. If I open an an encrypted but empty text file it seems to work but it might be random.
The encrypted test document is attached. The password is "test" without the quotation marks.

Not able to reproduce on Fedora 12 with 0.12.4, although it does produce a lot of " EvinceView-CRITICAL **" noise.

Which version of poppler is your version of ubuntu using? {looks like it is supposed to be 0.12.4, from  http://packages.ubuntu.com/source/lucid/i386/poppler)

Also renders fine on poppler from recent git, but that was only with the qt4 front end.

Comment 2 unggnu 2010-04-12 07:06:39 UTC

Yes, 0.12.4 is correct. I am going to try it with Fedora.

Does anyone know which patch might fix the issue?

Comment 3 Carlos Garcia Campos 2010-04-13 08:12:17 UTC

This a bug in evince, not in poppler I'd say. I've just fixed it:

http://git.gnome.org/browse/evince/commit/?id=2b60116df773bcd4456228ff79c3eff4264dcc4c

Comment 4 unggnu 2010-04-13 09:09:53 UTC

Thanks for the patch Carlos Garcia Campos but Evince 2.30 with your patch applied still crashes most of the time with my encrypted test pdf.

Comment 5 Carlos Garcia Campos 2010-04-13 09:14:53 UTC

Yes, I was trying with that one, then I guess there were two bugs, one in poppler that was already fixed and the other one in evince that I've just fixed.

Comment 6 Brad Hards 2010-04-14 03:15:59 UTC

I tried this with kubuntu 10.04 on an i386 virtual machine, fully up-to-date. Installed evince, opens and shows the document fine.

I can only say that it works for me.

Comment 7 unggnu 2010-04-14 03:31:29 UTC

The report in Launchpad got two duplicates with a similar crash. Maybe it doesn't happen with Kubuntu because of KDE.
It also doesn't crash all the time but most of it. I have tried it on three systems (one of them x86_64) and I could confirm the crash with my pdf after entering the password on all of them.

I am going to try the latest version in Lucid soon, maybe there was a fix already.

Comment 8 unggnu 2010-04-14 08:40:28 UTC

I still can confirm the issue with current Ubuntu 10.04 Lucid.

Comment 9 unggnu 2010-04-19 04:40:16 UTC

There is some new information from a new duplicate:

"PDF reader crashes when maximising window.

Steps to reproduce:
1. Double-click on password-protected PDF attachment in Evolution,
2. Evince starts and asks for the password,
3. Enter the password,
4. Evince opens the document on the first page,
5. Click the maximise button.

Expected behaviour
The window is maximised."

Comment 10 unggnu 2010-05-29 02:50:27 UTC

It seems to be fixed with Evince 2.30.1.
