 Here is a bug observed with TorBrowser 7.0a2 (which may have been there
 before), maybe linked to the interaction with the new guard algorithm:

 - after replacing a first bridge with one other bridge, through the
 "Configure" dialog, TorBrowser fails to connect, with many error messages:
 "[warn] Failed to find node for hop 0 of our path. Discarding this
 circuit."

 - to work with bridges again, need to erase manually the "Guard" line of
 first bridge in state file (with "listed=0" and "unlisted_since=..."), or
 put back first bridge (to get "listed=1").
