Turns out that I had customized the template for outgoing mail in /var/lib/bugzilla3/template/en/custom/email/newchangedmail.txt.tmpl
The new versions seems to use different variable names for some things, including the mail receipient. The old variable name expanded to empty, and the mail was sent to that empty address. Copying the default template ( from .../en/default/email), and backporting my changes manually (just displaying the product and summary for those who do not recognize the bug numbers) made things work. I don't know if it would be possible, reasonable, and easy to check for this kind of situation in the upgrade script. I leave that to Debian maintainers to think about.
