I have a very similar experience on Ubuntu MATE 18.04.
/run/user/1000/keyring/ssh is opened by gnome-keyring-daemon
/run/user/1000/keyring/.ssh is opened by /usr/bin/ssh-agent
$SSH_AUTH_SOCK points to /run/user/1000/keyring/ssh
When I try to open an SSH session to another machine it hangs just
Confirmed for 12.04.
This regression hit my library of 16000+ CR2 files when I migrated from
11.04 to 11.10, last year. I was hoping it would be fixed for 12.04 but
no such luck.
To make matters worse, if one selects say 10 RAW files opens them with
the Shotwell Photo Viewer, then one gets 10
