Hi, It works because it's bringing with him all required libraries, including the 'buggy' libQtGui (an older version, it seems). This is also why the appearance is not the same as the system, as its not using the parameters used at system level.
The issue with that approach is that: - those libs may need some security fix that you will never get - you have to install/uninstall the software by hand - it's overwriting some files installed by the package meaning that if you want to install the application from the website, you have to uninstall first the calibre and calibre-bin packages. Hope this helps, Fabrice -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/812258 Title: calibre don't launch and eat all ressource To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calibre/+bug/812258/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
