As I've already said I've no solution but some hints on how this issue could be handled: Catching this segmentation fault in a debugger and looking at the back-trace shows libX11 as the origin of the exception. Now you could look inside the source code of the X11 functions listed in the back-trace to get an idea what happens there, e.g. here: http://cgit.freedesktop.org/xorg/lib/libX11/tree Next you could put break points where the resource is allocated (NewDatabase) and destroyed (XrmDestroyDatabase). In case of the Qt display manager the database resource will be destroyed without creating it before. That's probable not optimal. In the next step you should run the same with the ogl display manager to see the right behavior.
