International character problem

Any folders that have international characters in their name seem to come and go randomly from the list on the left side of the screen. They're either all visible or they're all not.
Whether they are visible or not, the number of artists, albums, etc. does not change, so they're always in the catalog but sometimes not in the list. So this appears to be a display problem.
I have seen quite a few threads about this problem, but none of the suggestions in them have worked for me. I'm using Subsonic 4.0.1 on Ubuntu 10.04. This appears to be a defect. Has anyone found a solution for it?
