Did you disable/unload the GDB plugin in KDevelop settings before switching to "Debug" mode? That's the only possible scenario I can imagine causing this crash. Nevertheless, it shouldn't segfault in this case, of course.
This was reproduced on GDB plugin *disabled*! I didn't enable it since I didn't know the existence of it. It was disabled by default.
Reproduced.
It is possible to trigger this bug on KDevelop 4.7.0 Steps to reproduce: 1. Start KDevelop with enabled GDB plugin 2. Disable GDB plugin 3 Press debug button Backtrace: Program received signal SIGSEGV, Segmentation fault. indexOfMethodRelative<8> (normalizeStringData=<optimized out>, method=0x7fff2b397092 "controllerMessage(QString,int)", baseObject=0x7fffffffc6f8) at kernel/qmetaobject.cpp:525 525 ?
