Description Wegwerf 2016-04-25 15:45:03 UTC

When I create a new title clip and want to exit the title editor using the Ok button, Kdenlive crashes.

I've pulled recent Kdenlive git master, as well as MLT master. My system is an upgraded Kubuntu 16.04 with open source AMD drivers.

OpenGL renderer:  "Gallium 0.4 on AMD PITCAIRN (DRM 2.43.0, LLVM 3.8.0)"
OpenGL ARG_SYNC:  true
OpenGL OpenGLES:  false

The backtrace is as follows:
