I am using KDE 4.6.0 in openSuse 11.4
Here is the icon of the text file:

here is the icon when its zoomed out:

These two are so inconsistent. Second one is telling me that its css file. And at many times other files are shown as headers, python scripts etc. Is there any fix of this bug in later version of KDE / factory repos.
