I am having the exact same problem in Windows Vista.  I reinstalled Firefox 3.0.7 making sure Norton 360 was turned off but the problem remains.

I'm able to reproduce this every time on trunk and 3.5.2
1) create a clean profile
2) set firefox to restore windows and tabs
3) open about:config and set browser.tabs.closeWindowWithLastTab to false
4) close about:config tab
5) close firefox
6) open firefox again, error console is showing the error and "undo close tab" is empty

I can reproduce this with any "empty" session (just undo close tabs)

Strangely, this doesn't happen if you restart Firefox using a "restart" button (extension enable/disable, update).
Apparently the problem occurs at when saving "sessionstore.js" on shutdown, but it is reflected by this error on startup.
HTH.

One more thing, if you manage to save your last "sessionstore.js" before shutdown, you'll see that it has all the correct data, but after shutdown it's replaced with this strange 112 byte file.
({"windows":[],"selectedWindow":0,"_closedWindows":[],"session":{"state":"stopped","lastUpdate":1253547469036}})

So after looking at this a bit more, this is the same as bug 516605 and bug 500315, which are all dupes of bug 495123 (it's the same root cause).

Pablo, thanks for looking into this on IRC
