 Tor Browser Bundle 3.0 (every version, Linux and Mac OS X) sometimes fails
 to start the Tor Browser and hangs with "Connecting to the Tor network".
 Only after pressing "Open Settings" the browser opens.

 It seems that the bootstrapping on the restart is too fast and and the
 dialog hangs.

 Log output:

 The Browser only starts when the loading dialog shows up before the
 bootstrapping reaching 100% otherwise it hangs and doesn't show the
 progress indicator. It sometimes helps if you clear the cache under
 Data/Tor, because it slows bootstrapping down.

 How to reproduce:
 - start Tor Browser
 - exit it
 - start Tor Browser again
 - it will hang
