Failed to Conver HTML to FB2 in 0.6.24 Linux

[luqmaninbmore]

Greetings,

I have been attempting to make a nice FB2 out of an ereader html file and I upgraded to the most recent calibre so that I could get cover support. Unfortunately, the conversion to FB2 is failing now (it succeeded under earlier versions of calibre). I converted and EPUB to FB2 succesfully, so FB2 conversion is not entirely broken.

Here are the details:

The HTML you are feeding into the conversion is malformed. You said it is an eReader HTML file? is it an eReader PDB or is it HTML created from an eReader file with a tool like eReader2html.py?

Html from ereadert2html.py . The HTML itself looks good in a browser and on my Pocketbook 360.

FB2 Output requires compliant XHTML to be put into it. The one of the intermediate states in the conversion should be transforming the HTML your converting into XHTML. Could you open a ticket about this issue.
