Replacing the shipped libraries with the ones from here:

Funnily enough, on another server with Lucid and same RC version 0.7.2, the error does not occur, especially given that the folder only contains:
ls program/lib/Mail/ mimePart.php mime.php
These are exactly a Mail_Mime package, which is outdated in your system where the problem occurs. You can find required version numbers in INSTALL file.
