Hi, for the last 2 months, I have had a cron job download the ft on a daily basis and send it to my kindle using ebook-convert. Some 10 days ago, it stopped working with an error as follows (this error is repeated multiple times and then the program stops writing to output):

 Traceback (most recent call last):
  File "site-packages/calibre/web/fetch/simple.py", line 436, in process_images
  File "site-packages/calibre/utils/magick/__init__.py", line 133, in load
ValueError: Cannot open image from empty data string

I was still on version 2.48 and upgraded to 2.52, but still get the same error. But when I run manually from calibre, the download succeeds.

To my knowledge, I have not changed anything in my calibre setup or in my ft account.

I run calibre and ebook-convert on ubuntu 15.10.

Any ideas?

Thank you,

Piet
