The conversion goes through but when I try to view it, I get this stack error:
'PageTree' object has no attribute '_contents'
Traceback (most recent call last):
File "C:\Program Files\calibre\library.zip\calibre\gui2\lrf_rendere r\main.py", line 183, in parsed
File "calibre\gui2\lrf_renderer\document.pyo", line 472, in render

AttributeError: 'PageTree' object has no attribute '_contents'
I saw a similar thread
on this issue but the suspect was a DRM'ed PDF. In my case, I took an article from the NYTimes, saved as HTML and dropped it into Calibre.
