taglib-1.5: corrupted PNG-header while parsing APIC-frame

[Maxim Bourmistrov]

Hello,
taglib-1.5 stores a corrupted image-data while parsing APIC-frame with  
PNG-image inside.

Here is a quick, working fix to attachedpictureframe.cpp:

void AttachedPictureFrame::parseFields(const ByteVector &data)
{
   if(data.size() < 5) {
     debug("A picture frame must contain at least 5 bytes.");
     return;
   }

   d->textEncoding = String::Type(data[0]);

   int img_start, pos = 1;

   d->mimeType = readStringField(data, String::Latin1, &pos);
   d->type = (TagLib::ID3v2::AttachedPictureFrame::Type)data[pos++];

   img_start = pos;
   d->description = readStringField(data, d->textEncoding, &pos);

   d->data = data.mid(img_start);
}


Tested with PNG-image inside APIC-frame.
