I get this exception thrown whenever I use wicked shell on my linux box.

I forgot to mention, I'm using version 1.4.0 and eclipse 3.2.

Hi Joel,

I totally refactored the preferences and moved away from object serialisation to Apache XML Beans. With the 2.0 release, everything will work just fine (I tested it at my home linux system).

Regards and thanks for posting,
Stefan

PS: Sorry for the eternal delay of the response. I had some very busy weeks.
