Newbie question for Calibre: "Unknown Book Type" error

Calibre doesn't seem to be able to handle a few titles I downloaded from Amazon. I can't convert them nor can I view them in Calibre. For a couple, I get the DRM warning from Calibre, ok, stop.

But for the rest I get this "unknown book type" error. I googled it, and I checked the forums, but can't find the answer. It might be this topaz that everyone seems to be talking about, but i don't know how to check that either. It happens with at least 6 or 7 titles I have in my library. I thought Calibre might be 'broke' but I successfully converted a couple of Amazon books to epub format, so it works.

I am on a Mac OS X 10.5 and the iPhone is my ereader (for better or worse), and I have the latest Calibre 0.5.9.....Also, I think (that I have the right python version as well (2.6). Thanks for any help. Richard

Here's the error:

Unknown book type: ‡‡XVš.‡

Traceback (most recent call last):
File "/Applications/", line 55, in run
File "threading.pyo", line 477, in run
File "calibre/ebooks/epub/iterator.pyo", line 119, in __enter__

raise MobiError('Unknown book type: %s'%self.ident)
MobiError: Unknown book type: ‡‡XVš.‡
