Version: 0.6.80 (using 4.00.60 (KDE 4.0.60 >= 20080129), Gentoo) Compiler: i686-pc-linux-gnu-gcc OS: Linux (i686) release 2.6.23-gentoo-r3 Steps to reproduce: 1) Compile some *.ps file (I use some rather big file (~50Meg) and did not check if smaller files work too) 2) Open that file in okular 3) Recompile that file again (I use kile dvi->ps) 4) See okular crash Note: When I run okular in Valgrind, it does not crash.

Did you rotate your document in Okular before recompiling the .dvi?
No (well, not sure him, but i can reproduce the crash without rotating)
Hi! Even if it is outdated by now: No, I did not rotate the document. In fact, I did nothing to the document at all. (except recompiling it)
Can you reproduce the issue after r769283?
Hm, I would love to try, but after having recompiled okular, it cannot find any ps backends any longer. (Even tried recompiling the whole KDE4 system). So, if anyone can tell me how to open ps files in a recent version of okular natively again, I'll try to check if this bug is fixed :-)
Oh, never mind. I just found out that you use libspectre now for ps support. However, as there is no gentoo ebuild for that one, it might take a while until I managed to be able to display ps files in okular again.
You can always use kde4.0 branch that still embedds spectre in okular or bug gentooers to package libspectre or compile libspectre from source ;-) I'm closing the bug as with the pino patch it does not crashes anymore here. Feel free to reopen if after updating to something with this patch it you still get crashes.
Hi, as the person that filed this bug, I just wanted to confirm that this problem is indeed now fixed. @libspectre: The problem was that the gentoo kdegraphics ebuild refused to compile when I compiled libspectre directly from the sources. So I had to write an ebuild for libspectre first.
Created attachment 27650 [details] backtrace
@Carlo Buratto (comment #9): please provide a better backtrace, as explained in: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports Als, please provide a description of what happened...
I was writing a tex file, i compile it in a dvi and i opened the dvi with okular, then i reconpiled the dvi more times and okular automatically refresh the dvi, but sometimes (very few times) it crashes. However i recently updated my okular to 0.7.1 and i don't yet experience the crash. I'm sorry for the bad backtrace.
