Version:           2.3.2 (using KDE 4.5.3) 
OS:                Linux

When i browse through local files, Media Sources resizes automatically when directory path expands beyond Media Source's width. 
The main problem is that sometimes you cannot make it smaller again.
This bug is extremely annoying if you work on small screen. 
You have to restart amarok, in order to resize Media Sources to its inital size.

Reproducible: Sometimes

Steps to Reproduce:
1. Change the width of media sources (make it small enough).
2. Browse through local files and select a folder with large name.
3. If Media Sources is resized automatically, try to make it smaller again.

It reproduces after bug 256436 (https://bugs.kde.org/show_bug.cgi?id=256436) has been reproduced.

Actual Results:  
Sometimes Media Sources resize to show the folder path.
When it has resized, sometimes you cannot resize it to it's initial width.

Expected Results:  
In my opinion, it shouldn't resize it in first place.
Even if it did, you should be able to make it smaller again.

I have all 3 views (Media Sources, Playlist, Context) enabled.
It doesn't matter if i have enabled "lock layout".

As i mentioned before, it reproduces after bug 256436 (https://bugs.kde.org/show_bug.cgi?id=256436) has been reproduced.
I don't know if it occurs in any other case.
