I just reported bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1034563 .

After some minutes I got confirmation e-mail titled "Bug#1034563:
Acknowledgement (login: "su" doesn't put /sbin and /usr/sbin to PATH)"

This e-mail contained a link " https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=1034563 "

I clicked the link. And I saw a text:
==
Debian Bug report logs - #1034563
There is no record of Bug #1034563. Try the search page instead.
==
Then I updated the page and saw proper bug report page.

So I didn't saw bug report page immediately after clicking link from mail. This
is a bug

There's a short delay between a bug being filed and the bug being
distributed to the frontends. It's known, it's short, and it only
happens on new bugs.
