Reproducible: Always Steps to Reproduce: 1. Run DVD Wizard. 2. Add vob file 3. Click Next Happens with both Kdenlive 15.08.0 and current master (several commits ahead from 15.08.0). Qt 5.4.2.
I cannot reproduce. Some changes were recently made to the OpenGL code, can you please test again with a recent git ? Is this happening only sometimes or everytime you repeat these steps?

Yes, it still happens every time with the current master. openglContext() seems to be NULL in GLWidget::initializeGL() when creating monitor widget for DVD Wizard. Does it work for you with Qt 5.4.2 (just to be sure it's not a Qt bug)?
Meanwhile I tested 15.08.1. 1. Still segfaults with KDE 4, Qt 5.4.2 or Qt 5.5.0 and KF 5.14 (confirmed by other people). 2. Doesn't segfault with Plasma 5. Maybe you cannot reproduce the issue because you tried to do it only with Plasma 5?
I just tried 15.12.0. It doesn't segfault in KDE 4 but DVD Wizard dialog window hangs when pressing "Next" button.

Just checked kdenlive 16.04.3 (Qt 5.6.1, KF 5.24.0), still hangs in KDE4 when trying to create DVD with wizard.
