Hi Alexandre, Thanks for the report!
What an annoying edge-case :-). Essentially: controlling TTY isn't set
here.
An easier reproducer I wrote down when working on this code (with the fix):
$ setsid -w bts version
bts: WARN: Could not open /dev/tty despite STDIN being a TTY: No such
device or address
bts: Falling back to using STDIN.
[...]
I've added a fallback to just use STDIN in this case.
Thanks,
--Daniel
