This only happens with Safari! There is some kind of an error while processing the contents of the following page:
http://beszeljukmac.com/
Please take a look at the link in the left column, that says "Küldj nekünk e-mailt" (which means "sends us an email" in Hungarian). If you click on the link in Safari you will get a really strange email address. Try this is any other Mac browser, they all process this link the correct way.
The correct link should display:
info@beszeljukmac.com
Safari presents:
info@beszeljukmac.xn--com
If you take a look at the source code of the page in Safari the link shows up correctly, but in the rendered page the link brakes. This page worked in previous verions of Safari and it does work in every other browser. Is this a Safari Bug? We have not changed our site and this broke only after the recent 10.3.3 update...
