While testing a patch for legacy/trac#21753 I realized that PTs in general are currently broken with tor master resulting into output like ``` CMETHOD obfs2 socks5 127.0.0.1:41925 CMETHOD obfs3 socks5 127.0.0.1:41299 CMETHOD obfs4 socks5 127.0.0.1:34025 CMETHOD scramblesuit socks5 127.0.0.1:35225 CMETHODS DONE'. We only support version '1' Mar 16 13:03:05.000 [warn] Managed proxy at './TorBrowser/Tor/PluggableTransports/obfs4proxy' failed the configuration protocol and will be destroyed. ``` if started from Tor Browser. Bisecting reveals that this got introduced with 6e78ede73f190f3aaf91623a131a20cf031aad7e which fixed legacy/trac#21654.
