I'm also experiencing this bug in version 3.3.5 (Mac).
I'm using an rsa key (without passphrase) to connect to hosts in a group. I've specified which key to use at the group level.
I can connect if any random string into the passphrase box, but the unnecessary pop up is quite frustrating.
This key works without a passphrase if I connect using a local terminal.
