Trailing slash causes the relative links not to be processed correctly

It seems that trailing slash causes the relative links not to be processed correctly.

If, for example, there’s a root Updates.xml containing repositories with the following format:

<Repository action="add" url="../embeddedlinux/b2qt_container" displayname="Repository display name" />

And the repo structure is as follows:
 

<repo base>
    windows_x86
        root
        embeddedlinux
            b2qt_container
    linux_x64
        root
        embeddedlinux
      <etc...>

When the --add-repository argument is passed to the online installer with a trailing slash (i.e. <repo base>/windows_x86/root/ ) the additional content does not show up in the selection list.

However, the argument is passed without the trailing slash (or it’s populated in the "User Defined Repositories" list) - <repo base>/windows_x64/root - then the content is found correctly. The "../" in the link path appears to get ignored.
