Error converting to PDF from EPub and PRC

Hi,
I have been trying to convert an ebook from the PRC format to PDF and I keep getting the error mentioned below. I'm not changing any options/settings - everything is at default. (Of course, I had to change the output format to PDF).

<lots of stuff logged before this, then:>

Serializing oeb input to disk for processing...
Python function terminated unexpectedly
'OptionValues' object has no attribute 'preserve_cover_aspect_ratio' (Error Code: 1)
Traceback (most recent call last):
File "site.py", line 103, in main
File "site.py", line 85, in run_entry_point
File "site-packages\calibre\utils\ipc\worker.py", line 99, in main
File "site-packages\calibre\gui2\convert\gui_conversion.py", line 24, in gui_convert
File "site-packages\calibre\ebooks\conversion\plumber.py", line 919, in run
File "site-packages\calibre\ebooks\pdf\output.py", line 88, in convert
File "site-packages\calibre\ebooks\pdf\output.py", line 98, in convert_text
File "site-packages\calibre\ebooks\epub\output.py", line 170, in insert_cover
AttributeError: 'OptionValues' object has no attribute 'preserve_cover_aspect_ratio'


Could you please help?

Thanks.

this is a bug in the current release, will be fixed in the next release. You can downgrade toa previous release in the meantime.

Hi, Add converting CHM to PDF to the list.
I get the "AttributeError: 'OptionValues' object has no attribute 'preserve_cover_aspect_ratio'" at the end of the conversion and it fails.

Unfortunately, I can't downgrade to a previous release, because the previous release had a different bug converting CHM to PDF.

Glad to see you are on top of it though.. I'll wait. Thanks
