Description Andreas Kuhl 2010-01-08 18:12:36 UTC

Version:            (using Devel)
Installed from:    Compiled sources

Updated to KDE SC 4.3.90 (4.4 RC1) today. Since then, Okular keeps crashing on most PDFs with "Bogus memory allocation size". Some PDFs seem to work, could not figure out the differences yet.

Okular worked fine in KDE SC 4.3.85 (4.4 Beta2) with the same PDFs it is now crashing with.

What is the version of your Poppler library?
Can you attach the smallest public document that shows the behaviour?

Comment 2 Andreas Kuhl 2010-01-08 18:51:47 UTC

My poppler versions: http://pastebin.ca/1742975

I attached a public document which causes Okular to crash. Maybe the PDF generator is the criteria? All ghostscript generated PDFs seem to work fine, the Adobe Distiller ones crash reliably.

Old poppler, which most probably is the source of your issues.
Ask your distribution to update it (eg to 0.12.x).

Comment 5 Andreas Kuhl 2010-01-08 19:34:15 UTC

I opened an upstream bug in the Novell bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=569318

Comment 6 Andreas Kuhl 2010-01-08 19:52:11 UTC

Just to be sure: If the old libpoppler4 was the problem, wouldn't the crashes happen before on KDE 4.3.x? But they did not, the same PDF worked fine there...

Ok, I can confirm the RESOLVED UPSTRAM.

I saw that libpoppler4 0.10.1 recieved a patch fromthe openSUSE repositories which caused the trouble. Removing the patch fixed the issue. But since this was a patch with backported security fixes, I cloned the latest version of poppler from GIT, built and installed it. All PDFs work fine now again.
