Inexplicable wrapping

I have a problem with the string being returned from wp_list_categories in that the count values are being wrapped to the next line (((2) for Africa) for instance). The string itself does not appear to be wrong (well not in that respect anyway) the extract below is actual page output and there isnt an offending
or anything of that sort – anu other ideas?
