Version: 2.5 (using KDE 3.4.0 Level "a" , SUSE 9.2 UNSUPPORTED) Compiler: gcc version 3.3.4 (pre 3.3.5 20040809) OS: Linux (i686) release 2.6.8-24.11-default the following makes ark crash: # zip file.zip file.pdf # ark file.zip choose right-click on file.pdf an choose "view" ark does not seem to crash for other file formats (I tried postscript and ascii) and for other compression formats (I tried tar.gz and tar.bz).
Can you verify in Konqueror's settings, in the File Associations item, which application is listed on the top for application/pdf? Please tell us which one is at the top for embedding as well.
I can confirm, I have the same bug, and it seems to be with pdf files only. I'm on RC of kubuntu, with kde-3.4.0.

I can confirm this happens. kpdf is the top viewer for PDFs.
*** Bug 105822 has been marked as a duplicate of this bug. ***
Any idea why this is categorized as a kpdf bug? i can not understand why, if both kpdf and konqueror can embed the kpdfpart and not ark wouldn't it be an ark bug?
That's why I initiated the bug trace on ARK. Yet, I am not an expert though, not even plain newbie, so I can't say at all.
Albert: I couldn't reproduce the problem, nor find anything wrong in Ark's code to load the part (and, if there was a bug in it, i'd expect it to affect all parts, not only one, as the code is generic). As the backtrace suggests a crash in the KPDF part's constructor, I suspected it was a problem with KPDF. If you don't see any problem in KPDF, feel free to close the report as WORKSFORME.
I can not reproduce it either with kpdf and ark from trunk, are you sure the problem is embedding kpdf in ark and not that the file may be making kpdf crash? Closing as worksforme as suggested by Henrique, please if you can, try svn trunk versions of both ark and kpdf and try to reproduce the bug. If you still can reopen this bug.
I can confirm, ark+kpdf from trunk. Ark either crashes or gets in an infinite loop. The problem seems to be that both arkpart and kpdfpart define a singleton Settings class, with a static Settings::self(). When called from kpdfpart, I get to the Ark-defined method, basically getting a wrong pointer and reading junk. Funny, this happens only when running standalone Ark. Opening a pdf from within ark embedded in, say, konqueror, works just fine. Then again, I never really understood dynamic linking, name resolving and such... Originally I thought maybe because ark itself (the application) links to the settings class, but playing around with that didn't help. This might be compiler dependent, as well? Which would explain why it works for some... As a start, I´ll attach patches that change the names to ArkSettings and KPdfSettings, but perhaps a better solution should be sought? http://bugs.kde.org/show_bug.cgi?id=107566 seems like a duplicate, perhaps...
Created attachment 11829 [details] Settings to ArkSettings
Created attachment 11830 [details] Settings to KPdfSettings
Does applying that patches makes it not crash for you?
Yeah, fixes the crash for me.
Ok, i've applied the KpdfSettings patch, i'll contact Henrique and tell him to have a look.
