Greetings, I am getting an error when I try to start VirtualBox:

VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/usr/lib/virtualbox/VirtualBox.so",) failed: /usr/lib/libQtGui.so.4: undefined symbol: _ZN23QCoreApplicationPrivate19checkReceiverThreadEP7QObject

I have read the faq, it advised me to install a couple of font related packages, but these packages are already installed. I tried reinstalling libqt4-core, libqt4-gui, and virtualbox several times but this did not resolve the issue. I have also tried launching vbox as root and I still get this same message. Any help would be appreciated!

If you search the forum for this error, you will find other topics with different solutions. Those are not yet added to the FAQ.

None of the other posts were of help to me.

It turns out I had some residual qt4 packages from a kde4 repository that was turned off in synaptic/apt. This lead to a mismatch between the libqt4-gui and libqt4-core (these came from the regular hardy repos) packages, and the rest of the qt4... files on my system (they came from a kde4 repo). I removed the qt4 packages (including residual configs) from the kde4 repo, then reinstalled the libqt4-gui and libqt4-core packages. This solved the problem.

Hope this helps someone else.
