I think the problem might be caused by this cleanup: > - var extMgr = Components.classes["@mozilla.org/extensions/manager;1"] > + let extMgr = Components.classes["@mozilla.org/extensions/manager;1"] http://hg.mozilla.org/releases/comm-1.9.1/annotate/0e1adb3b9ac8/calendar/base/src/calTimezoneService.js#l146 But extMgr is later accessed outside this scope and fails.

Comment on attachment 409967 [details] [diff] [review] bustage fix Looks good. If this is not it, did you remove the stray extensions directory as noted in bug 470430?
Pushed to comm-central <http://hg.mozilla.org/comm-central/rev/1533f0738a3a> and comm-1.9.1 <http://hg.mozilla.org/releases/comm-1.9.1/rev/520d6289316f> -> FIXED
(In reply to comment #3) > If this is not it, did you remove the stray extensions directory as > noted in bug 470430? I did not found this directory on my system and it is not related to this bug. This bug occurs because we access undefined |extMgr| in case of Lightning, trigger an exception and fallback to the unit test section in the code linked above.
