Now I've tried it well and continues to crash :( I attach the two traces, I'll attach two core dumps (pre and post-crash) in the next comments, because they are huge.
I upgraded the following packages, and only them: - libqt4-dbg - libqt4-dbus - libqt4-declarative - libqt4-designer - libqt4-help - libqt4-network - libqt4-opengl - libqt4-qt3support - libqt4-script - libqt4-scripttools - libqt4-sql - libqt4-sql-mysql - libqt4-sql-sqlite - libqt4-svg - libqt4-test - libqt4-xml - libqt4-xmlpatterns - libqtcore4 - libqtgui4 ** Attachment added: "VBox_libqtgui4_traces_13.7z" https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/725959/+attachment/1879620/+files/VBox_libqtgui4_traces_13.7z -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to qt4-x11 in ubuntu. https://bugs.launchpad.net/bugs/725959 Title: libqt4 4:4.7.1-0ubuntu10, 11 and 12 produce segfault in VirtualBox (libqtgui4) -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
