288770 - browser.xml removeObserver call still sometimes throws exception

Status: RESOLVED FIXED

(Firefox :: Tabbed Browser, defect, P1)

Even after bug 283088 and bug 283116 the removeObserver call in browser.xml's
destroy method still throws an exception sometimes.  With a try-catch around it,
nothing after it throws an exception, so I think the solution is to put a
try-catch around just that one call so that the code after it still runs.

Note that I haven't figured out under what conditions it throws an exception,
but I log all of the stdout of my browser sessions, and it's not too common, but
it does happen occasionally.
