I know exactly what caused that problem. That problem is caused by the version of the DeDRM plugin you are using that inserts nulls in place of the Amazon watermark. This only seems to be a problem on OS X. If you are using OS X, update to Calibre 2.6. This has been fixed.

There is a version of the DeDRM tools that replaces the Amazon watermark with spaces instead of nulls. The nulls cause no end of problems. So it was changed to be spaces which do not cause any trouble at all. KindleUnpack had to be fixed to deal with these nulls.
