--- Comment #2 from Albert Astals Cid <aacid at kde.org> ---
It's not errors, it's messagebox popped up by the Javascript of the document,
could very well be anything, so no they can't appear anyway else.

I have not checked the code at all, but my guess the problem here is, that the
file does:

 If the field has an won focus -> show messagebox saying what the field
contents has to be

But that makes it lose the focus to the messagebox and win it again, so 

 If the field has an won focus -> show messagebox saying what the field
contents has to be


etc. etc.

Would need time to check that is indeed the problem and make it realize that if
it's winning the focus and had it and was lost because a mesagebox was shown,
there's no need to show the messagebox again.

And also check what Adobe Reader does with the file, because it's super easy to
infinite loop firefox too
