It would be interesting to try and narrow down the regression range here. This problem has been around for at least a month or so, possibly considerably longer.
Sigh. Regression window would be 2008-03-02 16:03, because http://mxr.mozilla.org/seamonkey/source/mailnews/base/resources/content/msgSynchronize.js#127 depends on the definition of msgWindowContractID that used to be in mail/base/content/mailWindow.js, and mailnews/base/resources/content/msgSelectOffline.xul thinks that by including mailWindow.js, it can save 15 characters of typing in msgSynchronize.js (at the expense of rather extreme action at a distance).
