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

[Francesc Vicent]

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.
