 I'm working on Tails Server and I'm currently implementing client
 authentication for it. When I use SETCONF to set the HidServAuth, or set
 it in the torrc and reload Tor, Tor crashes with this error message:

 Does this bug also exist in 0.2.8.6 and later?

 This bug does not exist in 0.2.8.6 :)
 But I found a similar bug: #20007
