Description Bartemius Crouch 2008-10-13 11:32:25 UTC
Version:            (using KDE 3.5.10)
OS:                Linux
Installed from:    Debian testing/unstable Packages

When I try to preview a file inside a 7z archive in ark, I get a blank preview. This is because ark doesn't extract well the file I want to preview, here is a test with strace, I open ark and click on "my.txt" to view it from inside ark : '''

% echo lorem > my.txt
% 7z a my.7z my.txt

Creating archive my.7z

Compressing  my.txt

Everything is Ok
% strace -f -e execve ark my.7z
execve("/usr/bin/ark", ["ark", "my.7z"], [/* 40 vars */]) = 0

'''

Notice that the file is named "my.txt", but ark extracts " my.txt", which fails. Looking in /tmp/kde-x/ark4VWj3m, I find no file.

I see a problem here : http://websvn.kde.org/trunk/KDE/kdeutils/ark/plugins/7zipplugin/7zipplugin.cpp?revision=869788&view=markup in p7zipInterface::processLine but I think this link is about ark in KDE4, which then has the same problem as ark in KDE3 (the one I'm using and I'm reporting the bug on)

thanks

Hi, and thank you for your bug report.
I have tried your method on the Ark currently in trunk, and it works fine. As 
for kde3 ark, there are no active developers so I doubt it's going to be fixed 
any time soon.
I do realize the current KDE release (4.1.2) does not have 7z support, but as 
soon as 4.2 is released I encourage you to try the new Ark with 7z support and 
more.

Here using:

Qt: 4.4.3                 
KDE: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2))
kdelibs svn rev. 899135 / kdebase svn rev. 899135
kdeutils svn rev. 899332
on ArchLinux x86_64 - Kernel 2.6.27.8

I think this is fixed.

I can open the 7z file, the my.txt file inside is listed and It can be previewed :)

Have you tried the KDE4.2.x Ark version ? Does it works for you? Thanks
