After update to karmic, ssh-askpass does not seem to work.

I just updated to karmic from jaunty, and now SSH always asks me in the console for the passphrase for my public key.
Before I got a graphical dialog box, I guess the one provided by ssh-askpass, and only had to enter it once per session, but now I got asked in the console every single time.
I've checked that I have ssh-askpass-gnome, and reinstalled it with Synaptic (mark for reinstalling, apply). I didn't try to end the session and try again, which I'll do after submitting this report.
