Problem with Calibre

[cistehovado]

Hello, I tried to use calibre, but 90% of my pdb collection shows error :
(they worked in my Palm T3, but I bought iphone and I tried to convert my collection to ePub format (coding is cp1250) ) could someone help me ?

The problem that appear in convert (is the same for all my books) :"AttributeError: 'NoneType' object has no attribute 'tag''"

here is the complete log from converting one book:

ERROR: Conversion Error: <b>Failed</b>: Convert book 1 of 1 (Cerveny a cierny)

Try converting with the --single-line-paras option. If that doesn't work try the --print-formatted-paras option.

The issue is the entire book is being read as one single (or just a few large) paragraphs. The default input differentiates paragraphs based on a blank line between them. The above two options change how paragraphs are detected.

Hello, I found a workaround for solution, I just set the SPLIT FILES LARGER THAN 260KB from default (260KB) to 512KB, and it works. (I hope books are converted successfuly )
