[Flac] Problem decoding .flac files

[Hal Vaughan]

This may be solved.

I'm sorry I didn't have time to post the offending file, but I noticed 
that the only files that had problems were ones I had ripped to my hard  
drive over a short period of time.  While I keep track of security 
updates if they effect the kernel or something regarding the direct 
functioning of my system, I don't if it's something like the Xine 
library.

When I saw the e-mail about a bug in the Xine library being fixed in 
Ubuntu, I thought I should be able to decode the problematic flac files 
again, but it didn't work.

Then, last night, when burning a few CDs that I could leave in a new 
classic convertible I just bought (I have a rule: don't leave anything 
in a convertible you can afford to lose, so only burned CDs), that's 
when it hit me: Only a few files over a short period of time were 
effected!

I grabbed some of the source CDs and re-ripped some of the problem 
tracks and they're working fine now.  I can decode those tracks now.

I'm going to put together a Perl script now and have it go through and 
test all the files in my archive (or probably all the ones within a 
certain time frame) and check them for errors.  Then I'll just re-rip 
all the files with errors.

I'm sorry I didn't have time to set up an ftp or web page with damaged 
files.  Things have been a bit hectic.

If it makes a difference, I can save the bad files so I can post them 
when I do have more time, in case that helps with trouble shooting 
flac.

Thanks for the help!
