Problem with Curl

Hello,

I am having a problem with curl. It can't access https://rubygems.org/ at all.

The site works fine. It can access https://whichever-other-site.tld/

Output:
http://fpaste.org/93688/13972572/

Working example:
http://fpaste.org/93689/39725745/

It seems like an NSS problem. I already tried deleting /etc/pki/nssdb
and reinstalling; but the results are the same.

Can't uninstall it completely since everything depends on it.

Any hints or ideas are welcome.
