trouble with ssl in midori on trisquel mini

If I attempt to trust a self-signed certificate in Midori on Trisquel Mini, it throws the following error:

Error granting trust: Couldn't find a place to store the pinned certificate
pkcs11:library-description=PKCS%2311%20Kit%20Trust%20Module

Searching the Internet yields a Midori FAQ page stating that I need to do some gymnastics with gnome-keyring. I've done this and I still have the same problems even after reboots/relogins/etc.

Anyone have any ideas on how to fix this? I'd rather not use another browser and this is getting frustrating.

Thanks!
