Comment:

 Okay, I am not sure where the "Circuit died due to an invalid selected
 path is coming from" (mightbe an additional bug) but the repeated "Failed
 to find node for hop #1 of our path. Discarding this circuit." and Tor
 essentially not working anymore afterwards is coming from git-
 690f646bf8a5de9b which made it into 0.3.2.7-rc.

 The case to repro is:

 1) Open a big news page in Tor Browser
 2) Select obfs4 as PT to use a built-in bridge
 3) Reload if necessary
 4) Switch to obfs3
 5) Reload if necessary

 Let me know if you need more info.
