From the error message this seems to be VirtualBox problem. The earlier Qt bug #1129061 (unrecognized OpenGL version) was fixed in Qt 5.2.0.

https://forums.virtualbox.org/viewtopic.php?f=3&t=60510 suggests an older VirtualBox might have worked better.

Another workaround is not using guest additions and letting LLVM software rendering do its work, but that's slow (both Unity 7 and the running Qt applications will be slower).

The most relevant upstream bug report seems to be https://www.virtualbox.org/ticket/12941 where also VirtualBox 4.3.6 (+ 4.3.14 guest additions) is mentioned in the last comment to have no crash.
