Conversion Error: AZW3 to EPUB

[Mary]

I purchased the attached ebook from Amazon and used the Apprentice Alf plug-in to strip the DRM upon import to Calibre. I can view the book in Calibre fine. However, when I try to convert from AZW3 to EPUB, I get the error (and accompanying details) below. I posted this in the Mobile Reads Calibre Conversion forum and someone recommended that it looks like a CSS problem in conversion rather than a DRM issue and I should make a bug report.

Also, as far as I can remember I haven't tinkered with any of the conversion settings in Calibre, but I can't swear to that since I've been known to try something I read on the Mobile Reads forums and then forget I did it.

I'm using Windows 7 64bit.
