So, let's see what I have:
1. *Tunnelblick: OS X 10.9.5; Tunnelblick 3.6.8 (build 4625); prior version 3.6.7c (build 4606)
2. It starts w/o any windows, just the icon in the tray.
P.S. Can it be related to ovpn configuration itself? Because it looks like I have similar behaviour with 10.7.4 and the same Tunnelblick version... Can't check it now.
In log:

Nothing suspicious in logs.
