After apt-get dist-upgrade on my debian testing system yesterday, some python packages, and in particular python-qt4, were installed.
So I decided to see if calibre would start, and it now starts normally. But perhaps there is a wrong dependency to python-qt4, since apt-get -t unstable install calibre didn't pull it from unstable? Here's the apt-get dist-upgrade that fixed the issue: edwards:/root# apt-get dist-upgrade Reading package lists... Done Building dependency tree Reading state information...
