I've found out that in version 4:4.7.1-0ubuntu12 actually suffers the same bug: VirtualBox crashes at the same stage (when insteracting with the guest OS). Thus, I've marked bug #727198 as a duplicate of this one and modified the summary.
I attach the traces from strace and gdb using version 4:4.7.1-0ubuntu12. In case you need more info, please let me know. ** Attachment added: "libqtgui4_traces_12.7z" https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/725959/+attachment/1878870/+files/libqtgui4_traces_12.7z ** Description changed: Binary package hint: libqtgui4 Before finishing the boot process of the guest OS (Windows7 64bit), VirtualBox closes unexpectedly and the following error can be seen in syslog: VirtualBox[12482]: segfault at 0 ip 00007faa37287a63 sp 00007fff35f443e0 error 4 in libQtGui.so.4.7.1[7faa37055000+a51000] Ubunty Release: Description: Ubuntu Natty (development branch) - Release: 11.04 + Release: 11.04 (x64) -- 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
