Package: gnupod-tools
Version: 0.99.8-2
Severity: normal
Tags: patch
gnupod_addsong fails to read metadata if the fieldnames are not in BLOCKCAPS.
This is contrary to the the Vorbis comment specification[0] (which FLAC uses
for its tags) which states "A case-insensitive field name that may consist of
ASCII 0x20 through 0x7D, 0x3D ('=') excluded. ASCII 0x41 through 0x5A inclusive
(A-Z) is to be considered equivalent to ASCII 0x61 through 0x7A inclusive
(a-z).". Some software (MusicBrainz Picard is the one I used) does not write
the fieldnames in BLOCKCAPS resulting in gnupod failing to read the metadata
correctly. Picard, for example, writes all lowercase fieldnames.

I have patched the gnupod_convert_FLAC script with the patch below which
corrects this behaviour (although there maybe a better solution).
