minimo SSL problem

Hi, I've been experimenting with minimo as in the mozilla 1.7.5 tarball,
just targetting at x86 for the moment.

I've got it to compile fine using the _unmodified_ defaults and build
instructions on the minimo web page.

The problem is SSL is acting weirdly.

If I run "TestGtkEmbed https://www.sf.net", the browser doesn't display
anything. Investigating with ethereal shows it does talk to the web server,
but for some reason thinks it send a bad certificate - I can see it sending
a certificate rejection message back to www.sf.net.

If I run "TestGtkEmbed http://www.sf.net", it works. If I then enter
"https://www.sf.net" into the URL bar, SSL works fine!

If I use another initial website, e.g. "TestGtkEmbed http://www.google.com",
and then enter https://www.sf.net, it fails as before.

It doesn't just affect sourceforge - all SSL websites seem to be like this
for me. I'm not using a proxy or anything...

Anyone have any ideas? This is driving me mad.
