SUMMARY
This is like bug 444862 but for two different pattern. When a new key is generated via ssh-keygen ksshaspass complains about not being able to parse these prompts:

ksshaskpass: Unable to parse phrase "Enter passphrase (empty for no passphrase): "
ksshaskpass: Unable to parse phrase "Enter same passphrase again: "

STEPS TO REPRODUCE
1. export SSH_ASKPASS_REQUIRE=prefer
2. export SSH_ASKPASS=/usr/bin/ksshaskpass
3. ssh-keygen -f /tmp/id_dummy

OBSERVED RESULT
No error message

EXPECTED RESULT
It actually works so this is more cosmetics. The error message should not appear though.
