Empathy ignores "remember this choice for future connections" on untrusted certificate error dialogue

When starting Empathy, if it tries to connect to servers that present untrusted certificates (in particular self-signed as with Gmail or Facebook), there is a check box to ask Empathy to remember the action for next time. However setting that check box has no effect.

Steps to reproduce:
1. Start empathy with a Gmail of Facebook account;
2. The untrusted certificate dialogue appears (see screen shot);
3. Click on the "remember this choice for future connections" check box;
4. Click "Continue";
5. Close Empathy (go offline or log out);
6. Restart Empathy.

Expected behaviour
Empathy should connect to the account without popping up the untrusted certificate dialogue.

Actual behaviour:
Empathy presents the untrusted certificate dialogue again despite the user request to remember the previous action.

Note: I completely understand that untrusted certificates are a security risk and that users should be notified. However, when it happens all the time on well know services, ignoring user requests to remember the action will eventually lead users to ignore that type of warnings and click through anyway.
