I seemed to found a solution myself: The problem arises when there are no right-blocks (empty). So, I put a " " at the end of the rightblock loop in the theme file, and ... problem solved :)
Ty for your reply anyway :)
PS: Great theme!

This is what I did:
<{if $xoBlocks.canvas_right}>
<{includeq file="$theme_name/blockszone.html" blocks=$xoBlocks.canvas_right
zoneClass='xo-canvas-column' zoneId='xo-canvas-rightcolumn'
}>
<{/if}>
