Failed restore: "All outgoing email has been globally disabled by an administrator"

I wanted to restore from backup (after the last upgrade from v1.9.0.beta13 to v1.9.0.beta14), but the restore failed.

It looks like it tried to rollback automatically…

But 30 minutes has passed and nothing happened except that this message does not go away:

Should i just wait a bit longer or something is stuck and i should do something to fix it?

There is a site setting called disable email, that you can just un check.
