Weird.  The error message seems to be coming from the (simple) table 
markup, not from mailto: .  Could you confirm that the page has a 
table on it -- i.e., is this perhaps a table of mailto: links?.

Do you still get the error if the mailto: links are converted into
normal text?

(And yes, this does appear to be a bug in the table markup, for
which I can issue a patch if we can confirm that this is the
source of the error.)

Thanks!
