Bug#551353: libwebkit-1.0-2: can't access to some local web sites using localhost hostname

[Denis Laxalde]

Package: libwebkit-1.0-2
Version: 1.1.15.2-1
Severity: normal

Some local web sites are not accessible through http://localhost:[some_port]/ via WebKit browsers while using the IP http://127.0.0.1:[some_port]/ works fine.
For example:
 - a MoinMoin "Desktop edition" (see http://www.moinmo.in/DesktopEdition), which should be accessible by http://localhost:8080/, only works with http://127.0.0.1:8080/
 - the administration page of Cups http://localhost:631/ works fine
