Subject: RE: Bugs(?) in 03/07 CVS
From: Nielsen Linus (ext) (Linus.Nielsen_at_elema.siemens.se)

I have now fixed this problem. It was indeed the ID3 reader that crashed.
It turns out that your file contains a very silly ID3 tag. It has the usual
ID3V2 header, but the only frame it contains is a 36K binary blob. Yes, 36K!
It was generated by RealJukebox and contains no seemingly readable text
information. I have searched the web for information on how to interpret
this blob, to no avail.

Out ID3 reader choked on the large tag and overwrote its buffer. I have now
added a protection against buffer overflow in the ID3 reader. Luckily, your
file had an ID3V1 tag at the end, so we could still display some ID3 info...
