Received this error while trying to forward a complex html email from ebay.
Unfortunately there is probably some PII embedded in it, so trying to
remove that to include the email might confuse things.
Any suggestions on how to find the error?

Thanks.

Does "M-x toggle-debug-on-error" yield a useful backtrace?

Is that HTML part confidential? My current guess is that it is
triggering a bug in the HTML parsing in GNUs. The call to forward-sexp
which is failing seems to be used (along with a special syntax table)
for selecting the region to be parsed by libxml. I do not see any
handling of malformed HTML in the corresponding function. Perhaps this
happens somewhere else, but another possibility is there isn't any
checks.
If the part is confidential, and you can isolate it, please run it
through some strict syntax checker. It could also be that the
assumptions about <> structure being balanced are violated in various
ways by syntactically correct HTML.
