Error: TypeError: aEvent.target is undefined
Source file: chrome://communicator/content/utilityOverlay.js
Line: 1418

http://mxr.mozilla.org/comm-central/source/calendar/lightning/content/messenger-overlay-sidebar.js?rev=3fe65676c36b#238

236     // call backs for the opt-out bar
237     let cbLearnMore = function(aNotificationBar, aButton) {
238         openUILink(kSupportUri, {});
239         return true;
240     };

SeaMonkey (and Firefox) expect that the second parameter is a real event or null.
Attached patch Patch v1.0 proposed fix. (obsolete) — Splinter Review
Alternatives:
openUILink(kSupportUri, { button: 0, target: { ownerDocument: document } });
openUILink(kSupportUri, openUILink.length < 3 ? {} : null);

What release do you need this for?

I think it would be better to differ using xul app info, or just initiate a real Event and pass that unconditionally.

If you go for the first solution, brackets even for one-line ifs.

This one is fine with me too:
