 I'm running TBB 6.5a3 with 6 obfs4 and 3 scramblesuit bridges. When I
 change networks (e.g. home -> work or cable -> wifi) and thus get new IP
 addresses, all URLs I visit in TBB time out. I tried to reload the URLs
 three or four times with the same result. But if I open the network
 settings, go to the bridge settings and press the OK button, everything
 works. So I make no changes to the settings. I just open them and close
 them.

 I copied the log from the TBB interface (I changed the original
 fingerprint and IP):

 }}}

 Steps to reproduce:
  1. Get some bridges.
  2. Change networks (get a new IP address)
  3. Enter an URL --> time out
  4. Open network settings, point the cursor into the field where bridges
 are set and click on the OK button
  5. Open a new URL or reload the old one --> site will open

 Do you need more information? Should I try to log with debug information?
