Shareaza

Hello. I have a Debian server running Sharelin 0.2.4, and a Windows computer running Shareaza 2.5.5.0.
My sharelin server has a 5 byte file called "hello.txt" with the text "hello". In Shareaza I search for the magnet link:
magnet:?xt=urn:sha1:VL2MMHO4YXUKFWV63YHTWSBM3GXKSQ2N
If fails. The Shareaza system log says:
Requesting download fragment (0-4) of "hello.txt" from 207.210.77.92.
Download host 207.210.77.92 responded with 500 (Internal server error).

The sharelin terminal on my server says:
Request error in uploader 72.1.139.125:59500 Invalid file info

I have successfully used Shareaza to download many other files from this Sharelin server. Any suggestions?

Thanks,
- Jeff

Fastest fix would be to ask sav. He should be able to say directly when Sharelin gets that error and that should narrow down if the problem is Sharelin or Shareaza.
