Bug report in TDE general UI and in K3B

Hi everyone, On TDE 3.5.13.1, when I go in a open/save file dialog, if i move between the files with the arrows on the keyboard, some items are always jumped, and when you press the down arrow and the highlighted file is the last in that column, depending on the files in that directory, it either go on the next column, as it should or it go to the top of the same column. I know that some persons will say that it is just a small papercut bug, but it wasn't present in KDE 3.5.x Also, when I want to create an audio CD from mp3 file in K3b, when I drag the mp3 file in the lower part of the screen, where the songs goes, I get an error message saying: ''Problems while adding files to the project.'' ''Unable to handle the following files due to an unsupported format'' Then, it says that I could go in another program to convert the files in WAV manually before adding them to K3B. This bug doesn't exist in KDE (3.x.x and 4.x.x) and I remember very well using this function of K3B back in 2006-2007, on KDE. The necessary codecs are installed and the bug can be reproduced very easily on my PCLOS livecd available on this website. It looks like a small papercut bug, but it is something that block me from using TDE on my main computer and in my opinion, K3B is the best burning app on linux, so using another program is not much an option here. Thank you in advance for your hard work on TDE! -Alexandre
