Geant4 Technical Forum (8 November 2011) - CERN
Sorry for not being more helpful here but without proper reproducibility of the problem it becomes almost impossible for me (also non Qt expert) to diagnose anything.
Since this doesn't look like a packaging issue I suggest you to post a question at the Geant4 forums:
possibly under the category "(Graphical) User Interfaces" or wherever you see fit.
keep me posted should you find some insight about this.
You are invited to attend a Space Users’ Workshop, co-sponsored by the Radiation and Effects Analysis Group at NASA Goddard Space Flight Center and the Vanderbilt University (Radiation Effects and Reliability Group). The aim of the Forum is to bring together Geant4 users across the space domain. The event will accordingly consist of a half-day Geant4 update, followed by two days of users’ presentations, and by a Geant4 Technical Forum where the Genat4 users and developers will review and define new space user requirements. The Space Users’ Workshop will be held in Nashville, TN on May 10, 11, and 12, 2003. The meeting location is in 134 Featheringill Hall, on May 10 and 12, and in 5326 Stevenson Center on May 11. Both locations are on the Vanderbilt campus.
