[TYPO3-rte] Error: Trying to copy RTEmagic files ... but one or both were missing

[Thomas]

Hello,

TYPO3 V. 6.1.3, multilanguage site.

I want to copy a content element from type "Text" with text and one image in the RTE over "Copy default content elements" in the second language, then the error display: 

[newlog()] Trying to copy RTEmagic files (uploads/RTEmagicC_typo3_image2.jpg / uploads/RTEmagicP_typo3_image2) but one or both were missing

But the content element, the RTE text with image, was copied correct in the second language.

Also found in the default installation under: http://introduction.typo3cms.demo.typo3.org

Does anyone know what I have missed or done wrong? 
How to clean up this message? Thanks.

Regards
Thomas
