[sws]

My automated scripts fail since I upgraded calibre to 2.1.
Whenever I try to fetch news, f.e.:

ebook-convert /home/sws/calibre-recipes/telegraph_uk.recipe telegraph_uk.epub --output-profile=generic_eink &&
ebook-meta telegraph_uk.epub --tag Tageszeitung &&
calibredb add telegraph_uk.epub

I get the following error:

1% Eingabe zu HTML konvertieren ...

  File "site-packages/calibre/ebooks/conversion/cli.py", line 359, in main

  File "site-packages/calibre/web/jsbrowser/browser.py", line 14, in <module>
ImportError: cannot import name QDialog

How do I have to change my scripts so I can fetch news again?
