Bug Description

Hello!

I'm using karmic with current updates. Yesterday libpoppler was updated: libpoppler5 libpoppler-glib4 and libpoppler-utils were updated to version 0.12.0-0ubuntu2.1. The attached PDF is a part of the draft of my thesis for university. When I scroll to the pagebreak and try to zoom in or out in evince (using Ctrl+mouse wheel) the system freezes completely and only a hard reset helps (no Ctrl+Fx or Ctrl+Alt+Backspace). I don't have any time to investigate this any further, because I've to complete my thesis, but the problem is 100% reproducible.

Sorry, didn't mean Ctrl+Fx, but Ctrl+Alt+Fx. Mouse won't move either...

whatever the viewer does the system should not crash, not a bug in the viewer

does the system recover if you don't touch it for a while?

Just checked the same document with ePDFview. This one works, so I think poppler isn't the problem. But when using evince, the system doesn't recover after 15 minutes.

I have the same problem (Xubuntu Karmic). It seems to me that evince mainly freezes the system when zooming large files or files that are not yet completely loaded.

Sebastien (comment #4): How long time should I give the system to answer your question? Is a couple of minutes enough? (this did not help)
I never get apport crash reports (I'm not sure it is enabled, but maybe it's also because of the system locking up totally).

Hello,
I do not get any system or program freeze with the crash.pdf file from comment 1. I can zoom in and out by using the buttons in evince or Ctrl+mouse and also change the window size at any place in the document without a problem. This happens on a Ubuntu 9.10 32bit (82865G Intel graphic card, 1GB Ram, desktop effects deactivated).

But indeed, today I encountered two complete system freezes (even magic keys did not work), when I wanted to change the window size of evince, while reading a document from the web. This happened with Ubuntu UNR 9.10 32bit on a Asus EeePC 1000H with enabled desktop effects.

I will test the crash.pdf there again and report here.

I forgot to mention that the fan got crazy both times the system froze on the EeePC 1000H. So I think the CPU load is at 100%... and after a couple of minutes, there is no recovery

I can confirm that also the crash.pdf file from comment #1 does freeze my system. I quickly zoomed to maximum and minimum with ctrl and the right part of the touchpad.
I assume the crash does not depend on the individual file. I regularly get it with pdfs like the one here: http://www.admin.ch/ch/d/sr/c210.html
My assumption is that the crash is triggered when evince gets input while still loading a page.

Hm, just checked the .pdf again... Works for me now, it's not freezing any more... I'm sorry, but I don't know the update that fixed this...

I confirm that I am now able to zoom as much and as quickly as I want, be it the documents I indicated in comment # 9 or BastiG's thesis excerpt.
Let's hope the bug's really dead, and thanks to the one who killed it!

I can't tell which update contains the fix, but it must have been published in the repositories between November 17 and today (December 9). If I understand the packages.ubuntu.com database and the contained changelogs, it can't be an update of evince or libpoppler (http://changelogs.ubuntu.com/changelogs/pool/main/p/poppler/poppler_0.12.0-0ubuntu2.1/changelog and http://changelogs.ubuntu.com/changelogs/pool/main/e/evince/evince_2.28.1-0ubuntu1.2/changelog).
