He, he... until somebody finds the reason you can just do the following::
1: Download LimeWire 2.7.3 Beta (Linux tgz file) from http://www.limewire.com/index.jsp/download_beta.
2. Do "tar xzvf LimeWireLinux.tgz"
3. To start LimeWire do: sh ./runLime.sh

That's all, now you have LimeWire 2.7.3 running with SuSE 8.1. Or at least Works For Me (tm)
