Version: 0.8.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.28-11-generic Bug first reported on the Ubuntu's launchpad https://bugs.launchpad.net/ubuntu/+source/kdegraphics/+bug/360647 (there is a traceback there) 1. Open a large DVI file with Okular (see an example of LaTeX source file bellow) 2. Compile the tex file 3. Okular crashes when refresh under certain conditions. At a certain point during the compilation, Okular remarks that the DVI is being changed. So it empty the content of the DVI being on screen (normal behaviour). At that point, if the LaTeX compilation still last some seconds, Okular crashes. I can reproduce the bug "at will" with the following trick : ------ Structure of a LaTeX file ----------- <Big LaTeX document (around 70 pages)> \input{foo.tex} \end{document} ------------ end ----------------- I suppose that the "big file" is just enough in order Okular to set itself in the "waiting" mode. \input produces an error which stops the compilation until I react. If I react sufficiently rapidly, no crash. If I leave some seconds without answering, Okular crashes. It seems to be really a matter of TIME between the moment Okular sees that the DVI is being changed and the moment where the DVI is actually finished.
Here is the output in the terminal : First : okular(15814): Attempt to use QAction "bookmark_action_0" with KXMLGUIFactory! Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) During the compilation of the big document : Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) Object::connect: No such slot fontProgressDialog::helpClickedSlot( const QString& ) ... and finally when it crashes : KCrash: Application 'okular' crashing... sock_file=/home/kusbiste/.kde/socket-geodiff-pc8/kdeinit4__0 A crash manager is automatically launched, but it complains that the backtrace is probably not enough.

I have exactly the same problem. Large file, and when the .dvi refreshes (from kile) it crashes.
Could you attach the files you use to reproduce this?
Created attachment 33352 [details] A LaTeX file which makes crash Okular when compiling The precise number of \lipsum needed to produce the crash varies from one computer to an other. The point seems to be the duration of the compilation.

Can't get it to crash here :-/
Btw, is anybody of the people who can steadily reproduce this problem able to compile from sources and/or try a patch?
This problem happens to me 95% of the time. My latex files are very big because there are many figures, that's why I cannot attach the files. I do not know yet how to compile from sources and/or try a patch, but if someone can explain it to me, I am willing to do it. I have installed a fresh ubuntu 9.04 with i686 kernel.
@ Albert Astals Cid Try adding some line (don't hesitate to put a lot of \lipsum). Maybe your computer is fast enough to finish the compilation before making okular crazy.
As I said before, I would like to contribute here but I just need some little help. I have been checking around and I have some questions (I know something about subversion and programming but not much) 1) I have found 'http://techbase.kde.org/Getting_Started/Build/KDE4/Kubuntu_and_Debian' with the pre-requisites to be able to compile kde4 programs but it has no explicit information for ubuntu 9.04. Is it the same as for 8.10? 2) I will be doing this in my only home computer or work computer so, in my 'production' machine, which I do not want to mess it up. Is there anything I have to take into account? 3) Do I have to uninstall my current okular before trying to compile my own? Thanks
SVN commit 972763 by pino: when attempting to open a DVI file, check whether the file is correct if not (for example it is still being (re)generated), then wait 800ms and try again, doing at most 10 waits this should protect against opening incomplete documents CCBUG: 189623 M +27 -0 generator_dvi.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=972763
The file *is not* correct. This is the main point of the bug. Here is the way to crash : 1. Open a correct DVI file. Everything okay. 2. Compile the tex file ... at this point, the DVI *is* being regenerated, *and* you leave it open in Okular. 3. If the compilation is too long and the file too large, Okular crashes. Notice that I do not *open* a DVI file being regenerated. What I do is to *leave* open a being regenerated DVI file. This is annoying because you have to re-open the DVI file each time you compile it. It was not like that when one opened DVI files with KDVI embed in konqueror (KDE3).
> The file *is not* correct. This is the main point of the bug. I *understood* that, hence my very recent commit (in trunk).
ow. Yes. I misunderstood. >when attempting to open a DVI file, check whether the file is correct you were describing the behaviour of your commit. I believed that you asked me more precisions about the bug :) Sorry for the noise, and thanks for the patch !

No problem; if anybody has the possibility to the newly added change to trunk, feedback about it is very welcome!
SVN commit 973366 by pino: the kpart does already loop when refreshing a document, so doing the "wait and try again" ourselves is not useful thus, then just do the check for document completeness before the actual opening attempt, should be enough CCBUG: 189623 thanks to Albert for remembering me okular already does many things automagically M +11 -0 generator_dvi.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=973366
SVN commit 973394 by pino: backport dvi document validity check please test once kde 4.2.4 is out CCBUG: 189623 M +6 -0 generator_dvi.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=973394
Well, I confirm that the bug is fixed. I'm installed Kubuntu, karmic koala. I have Okular version 0.8.80 with KDE 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1)), and no more crashes ... I could probably offer you a beer at next fosdem :)
Looks like there were no bad news about this, so I can guess this was fixed in 4.2.4 and some beta of 4.3. Closing then, thanks everybody for the feedback!
