When relaying http://stream.90elf.de/hq/mp3/testvbr with icecast, sometimes the server will stop streaming any data.

When connecting with wget, a HTTP 200 OK reply is sent but no data is streamed. Restarting the server sometimes helps and sometimes doesn't.

For now, we have the following observations:
1. The issue seems to be reproducible only with icecast 23kh version; the baseline icecast 2.3.2 seems to work fine.
2. The issue is sometimes (but not always) reproducible with clean icecast 23kh
3. When the issue occurs, the following lines can be found in the icecast error.log:
[2010-07-08 12:30:44] DBUG mpeg/get_initial_frame detected AAC MPEG-2, rate 12000, channels 4
[2010-07-08 14:55:13] DBUG mpeg/get_initial_frame detected AAC MPEG-4, rate 8000, channels 2
[2010-07-08 15:01:25] DBUG mpeg/get_initial_frame detected AAC MPEG-2, rate 88200, channels 2

Note that the stream contains no aac.
Note that the number of channels are bogus. The stream is a mp3 VBR stream.

kh24 has a number of changes for the mpeg detection and alignment. The same code handles aac and mp3 frames. The earlier versions did have some issues on detection but as far as I know, that detection is ok now.
