I use SUSE10.2 and everything seems to be working for me!
I had never used Xara before thou... so I don't really know how "to push it to the max". I have just one problem thou: I cannot export to SVG and I get the following error (a bug perhabs?):

Error from Xara Xtreme
Plugin filter reported an error but didn't provide a message

does that export function work for you?

I was able to export to other formats (Adobe Illustrator, Photoshop, etc) without any errors, but since I don't have these programs I can't really test the files that I have exported.
