They are:
Perdido Street Station by China Miéville (Pan Macmillan, Aug 2008)

The Rithmatist by Brandon Sanderson (Pan Macmillan, May 2014)

I don't see any obvious problems with either book after reconverting with KFX Input errors ignored.

I'm not sure if the above is useful information but I was surprised to find 0 hits on Google for this error. Either way, thank you very much for this plugin, it's let me back up 100s of ebooks, so I appreciate all the work that has gone into it.
Thank you for the bug report. Based on the ASINs in the logs I see that those editions are not available in my region (USA). I looked at the US edition of Perdido Street Station (ASIN B000FBFO8C) and it does not produce this error.

Those editions available to you appear to have KFX content that I have not yet encountered. Without an example to experiment with I cannot determine what needs to be done to this plugin to support it. If you PM me a link to a KFX file obtained by importing one of those books into calibre I will look into it further. (I understand if you are not comfortable doing that.)
