Package: libapt-pkg4.12 Version: 0.9.3 Severity: serious Justification: renders package unusable Hi, when running 'apt-get dist-upgrade', the command segfaults on amd64 after pressing 'y' in order to continue after the changes summary. The segfault happens in pkgPackageManager::SmartUnPack() (according to gdb). Looking at the backtrace, I suspect an endless loop filling up the stack space. This does *not* happen when running 'apt-get install <pkg>' (with extra packages being installed).
