Unfortunately this happens when clicking on a button in a Zimbra web admin interface so I can't provide a publically reproducible link. But the button executes some JS that should open a new browser window.

I can reproduce it with the method described in #801 (comment) (I think that comment belongs in this issue, as the error printed when crashing is the same)
