Comment (by s7r):

 I've seen this too, in 4.5a4 on Debian. I went to https://www.google.com/
 and got redirected to https://www.google.de (German exit relay selected).
 Tor Button was not showing circuit info for this tab. I had a hidden
 service opened in another tab, there Tor Button was showing circuit info
 just fine. Refreshed / reconnected few times to google, still couldn't see
 circuit data. Restarted Tor Browser, and it worked.

 Tried again and I couldn't reproduce it again. Tried on websites which use
 all sorts of redirects but just couldn't reproduce.

 Something confusing could be with providers like google who ship multiple
 services with one account. For example, I go to gmail.com and I am
 redirected to enter credentials to accounts.google.com/whatever. After
 that, I am redirected again to mail.google.com. From here I can navigate
 to other services related to the same account, such as drive.google.com or
 calendar or maps. Each will have a different circuit in this case.
 Currently it works, but there are some services which log you out if IP
 address changes during a session.
