HTML to EPUB conversion crashes

[jakev383]

I'm running Calibre 0.7.38 on Fedora 14, and whenever I try and convert a html book to epub it crashes. I've captured the crash output here:

ERROR: Conversion Error: <b>Failed</b>: Convert book 1 of 1 (The drowned world)

LookupError: unknown encoding:


I'm not sure what it means by unknown encoding. It successfully imports the HTML to ZIP, and only crashes when I convert to EPUB.
I've been saving them as text and then adding them back into my library and converting that way, but it's not ideal. Anyone have any ideas, or know of a bulk HTML to txt/PDF (I know, gasp!) converter that would make this easier on me?
Thanks!

You have an invalid encoding specified in conversion->look & Feel

Thanks. I looked and the encoding was blank. Changed to ascii and it converted successfully.
