Version: 2.4.90 (2.5 beta) (using KDE 4.7.2)
when using "Files" as media source in the left panel, there is a file explorer. At the top of this panel, there is the "Media Sources Home" button, a ">" and the location where the path of the current folder should be displayed. However the only part of the path which is displayed is "/".
Moreover, if you browse in your file system with a depth of 3 or 4 folders, when you change the size of the left panel you can see tiny windows appearing which contains each a button with the name of one folder of the path. The bigger the panel, the more windows appear. And if you reduce the size the windows disappear one at a time and they appear again when you augment the size. It is important to change of folder at least once after launching the file explorer if you want to reproduce this latter bug.
This bug is especially annoying with the tiling mode of kwin with the column layout, as if it is the only window, the window of amarok will be maximized, which means that the left panel's size will be augmented, which means that new windows will appear, which means that the window of amarok will be reduced and so will the left panel, which means that the windows will disappear and amarok will be maximized and it will start again. In this situation the window will be no more controllable as it will change dimension at fast speed.
Steps to Reproduce:
1.select the file browser as source
2.browse in your file system with a depth of 3 or 4 folders
3.resize left panel
if you increase the size, tiny windows appear with buttons corresponding to the folders containing the current one, if you decrease they disappear.
the folders should appear at the top of the left panel, and not in new windows
