When pinentry-tty is used to prompt for the password, interrupting the prompt using ctrl-c leaves the terminal only partially working: only some letter keys are echoed back.

The terminal remains in this broken state for about a minute, after which it resets itself and everything starts working again.

Below, I’m swiping through all alphabet and numeric keys of my keyboard at both 14.54, where only ”469+esgxb” gets through, and again at 14.55 (the last line), where they all come through.

14.54 jani@saegusa:testejä$ export LC_ALL=C
14.54 jani@saegusa:testejä$ { sleep 60; echo ”60 seconds passed”; } & LC_ALL=C /usr/bin/gpg -d passwords.gpg
