Hi, After playing a bit with the upstream 'package' (that include libraries) and the one in Ubuntu, I found that it's a bug in Qt: I'm able to reproduce the issue as soon as I use the system libQtGui.so file.
I found bug #805303 that seems to be the same, and if I use the workaround described there, I've been able to start calibre. the step I followed are: - install the qt4-qtconfig package - run qtconfig-qt4, and set appearance to motif instead of default one I'll keep this bug report open so that people having the issue can find it.
