Bug#800468: Second this bug 800468

[Pavel Mendl <pavel_mendl@centrum.cz>]

Just run into that. Symptoms are the same, even after reboot and apt-get 
install --reinstall dolphin.

KDE shortcut complains about  non-existing 
/usr/share/applications/kde4/dolphin.desktop , if this will help to trace the 
bug. 

Running from command line gives following:
$ dolphin 
"Trying to convert empty KLocalizedString to QString."

QPixmap::scaled: Pixmap is a null pixmap

Segmentation fault

Please fix soon, this bug is show stopper!
