File exists - Replace with Unknown:Unknown

when transfering a file the 'File Exists' dialogue pops up as expected with:

Existing File - 27465 bytes, Last changed 30/01/2007 18:16:43

Replace with - Unknown, Unknown

The existing file details are of the file to be transfered and not the file to be replaced.
It would seem that SIZE and MDTM arent supported and its not taking the data from the LIST -aL command
although the normal listings work fine.
