OK, I dont have access to Open Suse, but I have found two possible leads:
It is failing on treying to load a custom Look and feel called Liquid. This is not required by Jaikoz so I think it must be installed by default, according to thsi page
you can remove it by editing the swing.properties files on your system if you have one in your java installation folder, so please try this.
Secondly there appears to be a Suse related bug
which maybe causing this problem. the easiest way to test this out is to edit jaikoz.sh so that instead of saying
java -Xms64m -Xmx512m -jar lib/jaikoz.jar -l2 -m2 -f
java -Dawt.toolkit=sun.awt.motif.MToolkit -Xms64m -Xmx512m -jar lib/jaikoz.jar -l2 -m2 -f
You will also need to remove the dos eoln charcters in this shell script for it to work, I unfortunately I added them by mistake in the last release
please let me know how you get on .
