With 2 or more tabs open, close one then undo the close. At start the tab's title was in the window's title bar. On undo it's simply "Minefield" and no title. Switch to another tab and back and it will show correctly. Same effect using keyboard shortcuts or close button and menu. Can be tested with the initial two tabs of a new profile or any tabs thereafter. Tested on Kubuntu 10.04 and Windows XP SP3.
Beta 6 works fine, so it regressed sometime after that. (bit of a big window)
Maybe duplication of Bug 598221 - Page Title not shown in Title Bar on Session Restore
Just went through some old nightlies and got a regression range. First failure is on 20100918. Pushlog between those builds: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=268ef4ccb5ff&tochange=fc8d8dfee20f That's the same time as the regression range for bug 598221, so this looks like a subset of that bug seeing as undo is a single tab restore. Duping then.
