Second stack trace (id=85494) is not relevant to this issue. But the first one is still reproducible on Mac. 

Steps to reproduce:

1, start IDE
2, enable EB (download & install)
3, click link in Start Page
4, close EB component tab
Exc. is thrown.

Then tab disapeared but browser is still rendered in Main window, see attached screenshot.
