As I already told you, the bug was reproducible, as well in 2.4.0-test10 as in
2.4.0-test11. Today I tried it with 2.4.0-test11, the oops did happen again.
After applying your patch I ripped the song again (I figured out that it
was only one song, not the whole cd) and oops occured. Additionally
I checked the song out and it was ok.

PS: for unknown reasons your attached patch was included twice
in the file I saved on disk from it, so it came to this weird error messages
I mentioned in my last mail.
