Does this error still exist?

This was probably related to tickets 5019 and 4465 and was patched a week ago. You may want to check the patch.

I could reproduce it with 4.2.2, but not with current trunk.

Can you reproduce it with svn branch TYPO3_4-2?

Resolved, no change required.

As the reporter did not react to requested feedback for quite some time I assume this issue was solved meanwhile. Please reopen if this still occurs with recent versions of TYPO3.
