Works for me. :-(

I am pretty sure that is not true. For that to happen some Debian
developer would have needed to make a manual build and upload.

Can you reproduce this and show the exact error message?

I strongly suspect a local issue, e.g. locally built old version of
gnutls or nettle in /usr/local. "ldd  /usr/lib/chromium/chromium" might
point in the right direction.
