I installed the meshbuilder available from Ubuntu. When I want to load a mesh, it crashes. I think I installed qt4 as required, but it seems something is missing there. Here is the error message when loading a dolfin mesh.

Thank you for your help,

Benjamin: Either the dependencies of Qt 4.7 should be removed completely or a separate "Lucid" branch should be created.
