The mp3 file you are trying to edit does not have an ID3Tag:
Wikipedia: FF FB-> "MPEG-1 Layer 3 file without an ID3 tag or with an ID3v1 tag (which is appended at the end of the file)"

This case is already covered in the code at this line
Anyway you still need to explicit use the --create command line option to create a new Tag.

Can you give a bit more context?
What did you expect to happen?
Did you expect the file already has an ID3Tag?

Anyway I will improve the output of id3edit for this scenario so that it is more clear for the user what to do.

Thank you for reporting the bug.

Looks a bit like #20
Detection of missing ID3 header needs to be improved - well, handled in a better way than it is done now. :)
