A noticable difference between the working and the non-working systems, is the
change of SSL library from OpenSSL to NSS.

I think that if you can provide a curl command line against a public URL that
reproduces this or a similar problem, it'd be a great way to start debugging
this.

A fair test would also be to rebuild the modern libcurl with a recent OpenSSL
and see if that fixes the problems or not, as then we know if NSS is to blame
or if libcurl is!
