Step 1:

I received a mail with a URL like this: http://<jenkins-instance-uri>/job/<project>/53/display/redirect?page=changes

This is showing only a table of commits, but no log. The run is on a success state (green top-bar)

Step 2:

If I click on "previous run", on the top left corner, it goes back to the previous run, which was failing (red top-bar). This time a log is displayed, showing what was on error.

Step 3:

Now I click on "next run", going back to the run displayed on step 1, but this time there is a log. But the log is the one from step 2. So the log report errors, while there is a green top-bar and the real log is error free.

You can close the view, using the top right corner close button, to go back to the run list. Then if you click on the right run, you get the right log, error free.
