    there is a symlink/owner problem in the KDE file manager kfm. I found it
    on my SuSE 7.0 but I'm not sure if it is an original SuSE package or
    not, rpm doesn't know about it:

    paulps:/tmp > rpm -qfi /usr/opt/kde/bin/kfm
    die Datei »/usr/opt/kde/bin/kfm« gehört zu keinem Paket

    what means that the kfm binary is not known to rpm. However, I suspect
    that it is included in all KDE1 distributions.

    kfm will create a cache directory in /tmp without checking for correct
    onwership named kfm-cache-UID where UID is the numerical user id. Then
    it will write to files in the cache dir, for example:

    rootps:/tmp/kfm-cache-500 > ls -la
    drwxrwxrwx 2 rws uboot 4096 Apr 18 21:18 .
    drwxrwxrwt 15 root root 770048 Apr 18 21:16 ..
    lrwxrwxrwx 1 rws uboot 18 Apr 18 21:18 index.html ->
    -rw-r--r-- 1 rws uboot 0 Apr 18 21:16 index.txt

    rootps:/tmp/kfm-cache-500 > ls -la /home/paul/.bashrc
    -rw-r--r-- 1 paul users 1458 Jan 23 13:56

    and after running kfm as user 500:

    rootps:/tmp/kfm-cache-500 > ls -la /home/paul/.bashrc
    -rw-r--r-- 1 paul users 271 Apr 18 21:19

    The impact is obvious :-/
