Can you please be more specific wrt. what version of Tails worked for
you, and what version stopped working?

Looks like a bug in Tor sandbox rather than anything Tails-specific
to me.

Indeed, all those bugs should be fixed in Tor 0.2.6.x.

0. Make sure there are no AppArmor-related messages for Tor in `sudo
dmesg`. If there are, please report them to us.
1. Try without Tor sandboxing (configuring a bridge as documented via
Tails Greeter + Tor Launcher should be enough, since we disable the
sandbox when special Tor config is requested).
2. If #1 confirmed that the only problem is caused by Tor sandboxing,
report a bug on the Tor bug tracker: we don't maintain the Tor
sandbox in Tails :)
