Ogginfo 1.0 on Mandrake 9.0 says:

Processing file "this almost crashes winamp-ogg-vorbis 
only_audio_comp_vorbis_q4.ogg"...

New logical stream (#1, serial: 00000000): type vorbis
Vorbis headers parsed for stream 1, information follows...
Version: 0
Vendor: Xiph.Org libVorbis I 20020717 (1.0)
Channels: 2
Rate: 44100

Nominal bitrate: 499.821000 kb/s
Upper bitrate not set
Lower bitrate not set
Warning: EOS not set on stream 1
Vorbis stream 1:
        Total data length: 0 bytes
        Playback length: 0m:00s
        Average bitrate: nan kbps

Meaning it is zero-length.  WinAmp is just playing it over and over, and
not paying attention to messages in between.  Of course, if there was
supposed to be something in the file, the software you made it in may
not be working.
