Can't rename playlist titles

[kicker04]

Hi there!

I got a bug with the new version 2.0.4.
Every time I try to change the name of a title in my xspf-playlist this error occurs:

main debug: looking for meta writer module: 1 candidate
taglib error: File /Volumes/Die Simpsons/Die Simpsons/Staffel 23/S23E03 - Spider-Killer-Avatar-Man.mkv can't be opened for tag writing
main debug: no meta writer module matching "any" could be loaded
main debug: TIMER module_need() : 0.261 ms - Total 0.261 ms / 1 intvls (Avg 0.261 ms)

main debug: TIMER module_need() : 0.421 ms - Total 0.421 ms / 1 intvls (Avg 0.421 ms)

When I doubleclick on the title then to start it, the name of it will be deleted completely, either in the playlist and in the On Screen Display.

Please help!
