I do not have any assert message, and no gdk message on Kubuntu.
But your last backtrace is very different, you do not have a crash (i.e. a SIGSEGV): you have a SIGTRAP generated by the wxAssert dialog.
What is the message shown by the assert?
(the backtrace does not show any kicad code: all code is inside the wxWidgets and gtk/gdk libs)
