[TYPO3-english] tt_news click enlarge error

[Tony Lush]

After a site was upgraded to TYPO3 4.1.9, we find that url generated in 
tt_news for the popup window is malformed.

The link includes:

...onclick="openPic('http://www.domain.comindex.php?eID=tx_cms_showpic&...

which should be:

...onclick="openPic('http://www.domain.com/index.php?eID=tx_cms_showpic&...

All new news stories have this issue, whereas older news stories have 
proper links. Where is this URL generated?

Thank you -- Tony Lush
