#133 tag overwriting parts of mp3 blocks

[thomas kaeding]

I compiled id3v2 0.1.9 with id3lib 3.8.3 and ...
whenever a tag is added, the id3v2 tag is HUGE
(about 2kB of zeros added)
and both tags overwrite parts of mpeg blocks,
thus corrupting the audio file.

When compiled with id3lib 3.8.0 pre2, this does
not occur.

Here is an example:

> mp3check -e temp.mp3
[no error reported]
> /usr/bin/id3v2 -a Creed -t "What If" -g 6 temp.mp3
> mp3check -e temp.mp3
temp.mp3:
1504 bytes of junk before first frame header
valid id3 tag trailer v1.0 found
frame 12175/ 5:18: file truncated, 961 bytes
missing for last frame
[this file had 12178 frames before adding the tags]

I think that '1504 bytes of junk' are in fact your new fresh
ID3v2 tag. ;)
The added extra zeroes complements the tag thus the
resulting size to be multiple of 2048 bytes.
The actual problem is at the same end of your file, wherever
some part of the file data has eated by id3lib, because a bug.
Please, try patch #1027098. It may solve your problem.
