When we click on a link such as
http://kune.cc/#kune.docs.1111.959
Kune detects its a local link and doesn't open a new tab. However, if the link includes a locale:
http://kune.cc/?locale=es#kune.docs.1111.959
it fails to detect it as local link and it opens in a new tab. I dont know if it happens only when the locale is different to your default locale.
