VirtualBox fails to start with missing symbol in VirtualBox.so

[Alessandro]

Trying to execute VirtualBox results in the following error:

$ VirtualBox VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/usr/lib/virtualbox/VirtualBox.so",) failed: /usr/lib/virtualbox/VirtualBox.so: undefined symbol: _ZN11QTreeWidget17setSelectionModelEP19QItemSelectionModel

Operating system is Jaunty 9.04 (upgraded from 8.10), architecture is amd64. The same error occurs with both VirtualBox 2.2.4 and 3.0b1

Which VirtualBox package did you install (exact package name please)?

Please attach your /etc/apt/sources.list here.

[Alessandro]

Attached is my sources.list.

I have tested both virtualbox '2.2.4-47978_Ubuntu_jaunty' (using 'apt-get install virtualbox-2.2') and 'virtualbox-3.0_3.0.0_BETA1-48728_Ubuntu_jaunty_amd64.deb' found in the beta download section. Both display the exact same symptoms.

[Frank Mehnert]

Thanks. Please attach the output of

ldd /usr/lib/virtualbox/VirtualBox.so
dpkg -s libqtgui4

[Alessandro]

Output of ldd VirtualBox.so

This issue does not appear if I install the Intrepid version of the package on Jaunty.

[Frank Mehnert]

Which Qt version do you have installed in /usr/local? The Ubuntu packages don't install in /usr/local but in /usr. I'm quite sure this (an incompatible version of Qt4) is the reason for your problem.

[Frank Mehnert]

Closing because this is definitely not a VBox bug. Make sure no libraries from /usr/local are used.
