Description Thanos Kyritsis 2006-06-19 20:23:09 UTC

Version:           2.6.3 (using KDE KDE 3.5.3)
Installed from:    Slackware Packages
OS:                Linux

Ark crashes when trying to open Zip files made with PclZip 2.5 (PhpConcept Library Zip, http://www.phpconcept.net/pclzip/index.en.php).

I'll attach such a zip file in my next post.

The funny thing is that opening the zip file with Konqueror (and doing Select All, Copy, Paste) works. Gnome's Archive Manager also works. Various MS Windows Applications also work (WinRAR, WinZip, etc ...).
Command line tools also work (unzip). Midnight Commander, as well.

After Ark crashes, the familiar window pops up: "The Application Ark (ark) crashed and caused the signal 11 (SIGSEGV)". I'll paste the backtrace:

Comment 3 Haris Kouzinopoulos 2006-06-20 16:34:22 UTC

Ark crashes initially on this:
static FileLVI* folderLVI( KListViewItem *parent, const QString& name )

and more specific in
folder->setPixmap( 0, KMimeType::mimeType( "inode/directory" )->pixmap( KIcon::Small ) );

After commenting the line out, Ark continues to crash but i couldn't locate the exact position. All these FileLVI functions are not documented at all
