Re: [Easytag-mailing] Corrupted images on embedded art cover fles

[Jérôme COUDERC <easytag gmail com>]

Some informations about the related problems:

1) Black picture zone :
   The bug was fixed with gtk2-2.12.4 or gtk2-2.12.5. The last version 
is now available for Fedora 8.
So the problem was fixed.


2) Altered picture in other application
   The problem was due to a bug in taglib (library used by Amarok) . It 
does not support frames with unsynchronisation.  A patch was proposed by 
Alexey Illarionov to not use unsynchronisation in tag written by EasyTAG

Jerome
