[Bug 725959] [NEW] libqt4 4:4.7.1-0ubuntu10, 11 and 12 produce segfault in VirtualBox (libqtgui4)

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Chase Douglas (chasedouglas):

Qt has new multitouch support in Ubuntu. The current multitouch patch
does not properly handle the case where there's a touch event but no
widget where the touch occurred. When this happens, the qt library
crashes the application.
