dolphin opens a ghost window, whenever I open it

[Xwarman]

Binary package hint: dolphin

Description: Ubuntu lucid (development branch)
Release: 10.04
Dolphin
Version 1.4
Unter KDE 4.4.2 (KDE 4.4.2)

Whenever I open a dolphin window it opens a second one, as 'ghost window' I attatch a screenshot. I can close that 'ghostwindow' normaly by clicking on the right icon and work normally then with the other one. but its boring.

There seems also be a problem with the caracterset of dolphin. I had downloaded sth witch was unpacked automaticly. Now there are some chars marked as '?' in file- and directory names. if i try to rename, delete, move or copy those files or dirs there comes errors like 'file not found'

I tryed to open dolphin with another user account. at least the problem with the ghost window does not occour there. Another problem of my useraccount seems to be, that I cant logout, restart or shutdown the system from the k-menu. Whenever I try it, nothing happens. on another user account that workes normally too.
I found that passage in german user fourum ubuntuusers: http://forum.ubuntuusers.de/topic/kubuntu-reagiert-nicht-auf-herunterfahren/

Nachtrag: Hat sich erledigt. Es lag doch an der Änderung von Locale. Nach Rücknahme der Änderungen fährt der Rechner wieder herunter bzw. startet auf Wunsch neu. Offenbar bekommt KDE Probleme mit Dateinamen von Systemverzeichnissen oder Dateien, wenn man von UTF-8 auf ISO-8859-15 geht.

Last sentence means, that kde get problems with file or folder names when you change UTF-8 to ISO-8859-15. I does not do that knowingly, but the problem with the shutdown menu is since I reinstalled lucid from beta 2 disc.

Maybe you can tell me, witch settings I have to reset to fix my problem. (Please dont tell me to delete the hole .kde folder :-/ )
Thank you!

Ok, the ghost window problem is a settings problem. I delete all files in ~/.kde/share/dolphin and restart dolphin. now there is no ghost window anymore. but i think its interesting to know by witch settings the problem is caused.
