python 2.7: Getting Segmentation fault when setting Menu in GUI programming with Tkinter
The segfault is caused by:
helpmenu.add_cascade(label='Help',menu=helpmenu)after a quick look at the docs, it makes perfect sense why that would give you problems. Add cascade "adds a hierarchical menu item". You are adding helpmenu as a menu within helpmenu.
I believe that what you mean here is
menubar.add_cascade(label="Help", menu=helpmenu)
