Ark crashes with seg fault when opening zip file

[Chris]

Ark crashes every time I try to open / decompress zip file. With tar, tar.gz everything works fine.
Crash handler reports Seg fault, but fails to create a backtrace because of missing debug packages.
Which debugging packages should I install?

Application that crashed: ark
Version of the application: 2.13
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-5-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
<In detail, tell us what you were doing when the application crashed.>

 -- Backtrace:
An useful backtrace could not be generated

Report to https://bugs.kde.org

Could you please install kdeutils-dbg and paste the backtrace from the KDE crash handler? Thanks.

[Chris (cpeter1)]

I already have had installed kdeutils-dbg, but no backtrace is generated, except the seg fault feedback I have posted above. Which other information would help for debugging?

[Adam Reeve (adreeve)]

I get similar behaviour. Ark crashes sometimes when opening zip files, but other times it doesn't. When it does open them, extracting has no effect. It's as if everything works fine but no files are actually extracted. Extracting the files from Nautilus in Ubuntu works fine.

I'll try and generate a backtrace later with the -dbg package.

[Adam Reeve (adreeve)]

I couldn't generate a backtrace either. I get this output on the terminal when opening a zip file from ark:

KCrash: Application 'ark' crashing...
sock_file=/home/adam/.kde/socket-adam-desktop/kdeinit4__0
QFile::at: Cannot set file position 0
ark: Fatal IO error: client killed

I don't know if that "Cannot set file position 0" is related to ark or KCrash and if it's helpful at all.

I get this in my ~/.xsession-errors:

kded(3868) Mollet::KioSlaveNotifier::onDirectoryEntered: "file:///home/adam/Downloads"

The laplace_inversion_gavsteh.zip file is what I'm trying to open, I'm not sure why it's looking in the RecentDocuments directory, I opened it from ~/Downloads.

I tried to generate a backtrace in gdb and got this:

Thanks. This looks like https://bugs.kde.org/show_bug.cgi?id=192798 which should be fixed in KDE 4.3 beta2 coming this week. :)

[Jonathan Thomas (echidnaman)]

Fix released to the development version of Kubuntu 9.10.
