Ok I have problems wiht my Kfile plugin for displaying Meta-Info for FreeBSD 
*.tbz packages, it behaves strange when I open a dir containing 2 or more
packages. I do a right click on packag1.tbz and view  the Meta-Info but there 
isn't any, I reload konqueror and now it works but it now shows info for 
package1.tbz on package2.tbz, info for package2.tbz on package3.tbz and so 
on.

Here is my source code, where is the problem please help me

// My header file
#ifndef __tweakBSD_pkg_H
#define __tweakBSD_pkg_H

#include <kfilemetainfo.h>
#include <qprocess.h>


class QTextView;

args);

    QProcess *proc;

    void readfrom_pkginfo();

    QString getComment();
    QString getDescription();
