Version: (using KDE 4.1.96)
Installed from: SuSE RPMs
The taskbar entries for minimized windows don't use the right button style when using composition in Kwin and thumbnails for all windows are enabled. Instead they appear as inactive windows.
How to reproduce:
* You need composition enabled in Kwin.
* Go to System Settings > General > Desktop > Desktop Effects > Advanced and change "Keep window thumbnails" to "Always"
Check the attached screenshot.
Note: I am not sure if this is a plasma or a Kwin bug. Feel free to change the report if the latter is true.

Normal vs Broken
Kwin devs: does kwin not actually mark windows as minimized when thumbailing is "always"? if so, is there another hint we can be looking to distinguish minimized windows in this case?
I found another affected case that must be related.
Setting thumbailing to "always" causes alltray to stop functioning correctly. Hide/unhide won't work.
It might affect a number of other software. Please have a look.
