Version:           2.1.1 (using KDE 4.7.4) 
OS:                Linux

I'm working on Ubuntu 11.10 64-bit. I use the German Version of digiKam. As suggested in Bug 284740 ("Can't change theme") I installed the KDE system settings control center via synaptic and I was finally able to change the default theme, respectively the theme in general. 

However, the changes obviously only affect the main window of digiKam. The album explorer on the left of the main window has still a white background and - depending on which of the dark themes I use - either with an unreadable yellow or light grey font. I can't change anything in the album explorer via the contrel center. The bug remains even after a digiKam- and also a system restart.

I would be more than grateful if someone had a solution for this bug since apart from this digiKam is a great application. To make it easier I attach a list of packages I've already installed to get the dark digiKam theme running correctly:

Reproducible: Always

Steps to Reproduce:
Started digiKam - selected "Einstellungen (Settings) - Design - Einstellungen to launch the settings control center for the themes. Selected a theme and changed the colors. Pressed "Apply" and "OK". Restarted digiKam with the same result. The album explorer remains white. Tried it with other themes with no success. Downloaded via the control center a dark theme called TeaSun, applied it, restarted digiKam with no success. Restarted the PC - started digiKam again, no success. Still a white album explorer.

Actual Results:  
Everytime I start digiKam the album explorer has a white background whilst the main window "accepts" the theme currently selected (in my case a dark theme). Because of the white background of the album explorer the album names are almost unreadable and the entire layout of the GUI looks quite weird now. Especially when I click on e.g. batch processing in the menu. The following mask is a mixture of parts of the dark them and whited-out parts with unreadable font where I can choose the files.

Expected Results:  
The entire GUI including the album explorer should use the selected theme.
