It seems that my previous ticket about same issue disappeared without trace.
Version information: 0.4.3. No additional plugins.
Steps to reproduce:
1) Open piwik and log in
2) Open same piwik to another browser tab. Logout
3) Go back to original browser tab and click dashboard
What is expected: clean redirect to login page.
What is happening: see attachment. Quite unclean login page (navigation is there and header row shows that user is logged in).
Attachment: Screenshot of UI fail
Please read comments in #966. I couldn't reproduce your original test case with the latest code in SVN.
Hack. Tested on FF3.
(In ) Update msg which would be displayed when a user logs out & then reload a page with a site that he can't access, refs #975
