Bug 243434

Can you please attach the chm document that causes the crash.

It's too big, and it's not mine :P

Can you reproduce the bug all the time?

Well. You're right in that it probably is a duplicate of that other bug, since if I don't use the sidebar it doesn't crash. Only when I loaded the sidebar with thumbnails then it crashed. 

and yes with thumbnails on it crashes all the time with this file.

I've got an extra piece of information which I think will be usefull.
Some of the pages are LOOOOOOOOOooong. Like 3 or 4 or more pages high, altough only the top part has text. I guess it's not a very well formatted chm file. Who uses this format anyway :P lol

Can you please run 
valgrind okular /path/to/my/file/that/crashes.chm
in a shell and make it crash and attach the output

Hi,
I have the same problem with okular version 0.11.2
I confirm that the problem disappear if I disable the side bar.

The problem appears each time I open the document I'm going to attach
Bye

Created attachment 55283 [details]
pdf doc

Can someone please what i asked and do
valgrind okular /path/to/my/file/that/crashes

Here it is.
I can open this document on my PC, only on my brother's PC I can see this crash.

I'm sorry but the development packages are not available, 
so I can't produce a better report

Can you please install debug symbols and run it again, wihtout it is really not much useful. Read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Preparing_your_KDE_packages if you need help installing debug symbols

@lordyoukai: better if you run

New crash information added by DrKonqi

okular (0.11.2) on KDE Platform 4.5.5 (KDE 4.5.5) using Qt 4.7.1

- What I was doing when the application crashed:

Opening any PDF.

#32 is that really the valgrind trace you get? It doesn't make any sense and it's totally different from the gdb trace :-S

Yes, this is what valgrind gave me, you can see from valgrind's output:

==18617== Command: okular 02_AT_Quote_SPQ.ID.OPP-000008958.pdf

I was opening the same PDF as for the crash in the backtrace.

Also I noticed that when I open okular remotely via NX, I don't get a crash. Both machines are running FC14.

Hi,

as I saw this valgrind discussion, I run my one as well with valgrind.
What happens is:
after started once with valgrind, it works even without valgrind.
I got that for the pdf and the dvi output (details see bug 264168)
Here the valgrind output for the DVI version, but it did not crash, which I could reproduce the crash before always.

Achim valgrind log makes much more sense.
#34 I find interesting the comment you make about NX not crashing as it shows it's maybe not Okular's fault. So can you guys try using different window managers kwin/compiz/metacity with and without effects enabled, and/or different/newer X drivers and/or diffent hardware if you have access to it and see if you can still reproduce the problem?

I just installed kde-standard package from squeeze (debian), so 4.4.5.
same issue:
Application: Okular (okular), signal: Segmentation fault
[KCrash Handler]
#6  0xb395d19a in PagePainter::scalePixmapOnImage (dest=..., src=0x87a68a0, scaledWidth=991, scaledHeight=1401, cropRect=..., format=QImage::Format_ARGB32_Premultiplied) at ../../okular/ui/pagepainter.cpp:755

....

And again okular does not crash when started under valgrind.

Different hardware for X is quite diffcult for me, the box is really old.
The current nouveau driver detects a NV05 Chipset (Riva TNT2?)
But for sure there are no effects:-)

So I have this issue with LXDE and KDE 4.4.5.
I could try to upgrade to the 4.5 repository from debain, do you thik this helps?

Now after upgrade:
okular --version
Qt: 4.7.1
KDE Development Platform: 4.5.3 (KDE 4.5.3)
Okular: 0.11.1

And the result:
Application: Okular (okular), signal: Segmentation fault

And again it still works when using valgrind (but it is unusable slow:-)

Are you all by any chance using the "raster" graphicssystem instead of the "native" one? i.e. does okular crash if you run
okular -graphicssystem native myfile.pdf
?

Actually the opposite has helped. With native it crashes, with
okular-graphicssystem raster it works most of the times. But sometimes
still
crashes.

Is it possible to save the graphics system preference somewhere ?

I also tried updating NVidia driver to the latest version, didn't help.

Thanks for the work around. Unfortunately I can't replicate this
because I installed a new OS, but I'll try this if it crashes this way
again.

Okular does not work very well on Opensuse  KDE, so i dropped it.
And I use now Acrobat that works much better.
I do not understand : if the same error occured, since when ?

Created attachment 63129 [details]
New crash information added by DrKonqi

okular (0.12) on KDE Platform 4.6.00 (4.6.0) "release 6" using Qt 4.7.1

- What I was doing when the application crashed:

I was clicking in Konqueror on a pdf file (same crash, if leftclicking with direct opening or rightclicking and selecting okular in context menu). Shortly after start, okular crashes.

I have reported that earlier.

New information is following:

- Custom settings of the application:
It seems to depend on the setting of "creation in background" in "Einrichten->Leistung" (Preferences->performance). If set, okular crashes. This can be reproduced.

Hope, this will help to fix it.
