I've upgraded from 9.3 to 9.4.0.5133, and after this update I don't see any objects in the db tree on the left.
The schema's are there, and when I configure the tree to group objects by type, i do see the number of items, but I don't see the items themselves.
I've turned debug logging on:

In the screenshot you see how it looks. The schema's show, but the tables and other menu-items remain empty when you expand them.
Note: this was working fine on this machine until I've upgraded HeidiSQL.
