Many webpage not available errors in Android 4.3

[slackhead]

I'm guessing that this could be a webview bug because the "small app" browser that came with the phone also has this problem. It's a Sony Xperia 1.

An Example is the f-droid forum. I get a "Web page not available" error page. Works find in firefox and opera. I can even long press the link in the error page and open it in firefox or another app with no problem.

I did a little debug test by using privoxy on my laptop as a proxy and watching the connection. It seems to connect OK. I don't see any problems in the output.
