Whoops, I should have put a little more effort in preparing the example.
Without the Gaphas dependency the code looks like this:
from gi.repository import Gtk
class MyDrawingArea(Gtk.DrawingArea):
def do_realize(self):
Gtk.DrawingArea.do_realize(self)
def main():
win = Gtk.Window()
view = MyDrawingArea()
win.add(view)
win.show()
view.show()
win.connect('destroy', Gtk.main_quit)
Gtk.main()
if __name__ == '__main__':
main()
But the results are the same, SIGBUS error with an identical stack trace:
