Can you reproduce the crash at will ? Can you reproduce the crash if you launch okular as "okular -graphicssystem native" on Konsole ? Thanks
It does happen at will with this pdf file. It does still happen with '-graphicssystem native' also. The backtrace looks the same when it crashes with -graphicssystem native.
Weird, it should not look ~the same~ Do you have Qt4.5.2 available to install ? Thanks
works without any crashes here Okular Version 0.8.90 Using KDE 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2)) I downloaded the file and completely scrolled up and down 3 times both normally and opened with okular -graphicssystem native UFB50.pdf
Note that the original poster uses Cleanlooks style, to reproduce, you should try with "-style cleanlooks" too.
just tried with cleanlooks, still works, I even tried zooming in and out and switching the continuous mode on and off, I have not been able to crash okular
Trying here using: Qt: 4.5.2 (KDE-Qt git commit 46a247a2c9a8c0c4456a02f6a0922d859d88fe76 Date: Fri Jun 26 13:45:37 2009 +0200) KDE: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090706)) kdelibs svn rev. 997539 / kdebase svn rev. 997539 kdegraphics svn rev. 998742 poppler 0.10.7 on ArchLinux i686 - Kernel 2.6.30.1 Scrolling the testcase PDF document: - Using Skulpture: it doesn't crash - Using Cleanlooks: it doesn't crash neither. I even tried with Cleanlooks+ forced Raster engine+ different Okular options (different zoom levels) and it didn't crashed. Do you use any other non-default option at Okular ? It could be a heisenbug, or it could be fixed on Qt4.5.2+ Thanks

Ok, marking as WORKSFORME. Reopen if you experience the crash again. Thanks
