I had a similar problem within another location on the back-up HD. This time it was with a folder, containing audio files. I could not enter it and, furthermore, it was displayed and estimated as empty by Dolphin. I even thought it had to be so, as I tried to go further out in the directory tree to see if the expected size of the folder were estimated into the total amount there. And, according to what mentioned previously, I restarted dolphin to see if things (the size) changed, still the same. This was different to how Dolphin and Konqueror behaved towards the files directly, all of the audio files in the directory, mentioned previously, was displayed and estimated with the correct size. That is to say: everything with the file was apparently correct until trying to activate the file. Not so with the folder example. I also tried to enter the folder from Konsole whitout any luck: ‘There is no such directory (…).’. But, again, browsing through audacity shows clearly that the files stored in the ‘non-existing folder’ are there. They are accessible and playable.
A sollution, thus, is to open every ****ing file with Audacity, resample, convert or just rename or re-tag, or something else(?), and save them in the directory where they initially were (before being backed-up). I have not explored further what the possible cause more preciesly could be, but, as I mentioned previously, fonts, wether it was far fetched or not, is not the issue it seems, as I had several other both folders and files whose name included those letters. There was no problem copying (accessing++) them.
I haven’t really got a clue:shame:, but it seems likely to me that it has its origin in kde4 possibly qt4? I never had this problem in kde3. I am probably a bit biased and, perhaps unreasonably, sceptic towards kde4. I do not think I had changed desktop if kde3 had been developed further. However, kde4 looks splendid, lets hope all the(my) greatly missed applications, Kaffeine and Amarok will be back on form soon.
Well thanks for reading, and comment if you want to. A bit strange if I am the only one who experience this, well well.
Cheers
