TYPO3 Core

Situation
TYPO3 6.2.5 (and 6.2.4)
We have A-Tags without href in &L=1 together with pages of type shortcut, if the configuration of L=0 and L=1 is different.

How to reproduce
Generate a simple HMENU

page.20 = HMENU
page.20 {
    1 = TMENU
    1.expAll = 1
    1.wrap = <ul>|</ul>
    1.NO = 1
    1.NO.wrapItemAndSub = <li>|</li>

    2 < .1
    3 < .1
}

Generate a page of type shortcut with some subpages:

In Default language the shortcut_mode is set to "Selected Page" and a page was selected in "Shortcut Target":

In the additional language &L=1 we choose "First subpage..." in field shortcut_mode and let the "Shortcut Target" empty:

Now in Frontend there is an empty A-Tag (href is missing) in &L=1:

<ul>
  <li>
    <a>Shortcut L1</a>
    <ul>
      <li>
        <a href="index.php?id=25&amp;L=1">Page 1</a>
      </li>
      <li>
        <a href="index.php?id=26&amp;L=1">Page 2</a>
      </li>
      <li>
        <a href="index.php?id=27&amp;L=1">Page 3</a>
      </li>
    </ul>
  </li>
</ul>

My lanuage settings are pretty simple:

config.linkVars = L

config.sys_language_uid = 0
config.language = de
config.locale_all = de

[globalVar = GP:L=1]
   config.sys_language_uid = 1
   config.language = en
   config.locale_all = en_EN
[end]
