Thanks Nicholas for the reproducer! I tried some variations to narrow
down the scope (as it's not easy to get an actual crash/core
dump/backtrace of that):
* With gnome-calculator it doesn't crash (GeditWindow → MathWindow,
GtkToolButton/name='EditUndo' → GtkButton/BuilderName='calc_undo_button'
* With gedit it doesn't crash if I call self.app.select_single()
instead of self.main_window.select_single(), i. e. the additional
self.app.select_single('GeditWindow') in the loop (through the
main_window property) is significant.
We have a very similar stress test in the test suite already (from the
last attempt at fixing that): http://bazaar.launchpad.net/~autopilot
/autopilot-
gtk/trunk/view/head:/tests/autopilot/tests/test_properties.py#L140 .
Bumping that to 1000 and up doesn't crash, but this uses self.app.
* I tried to make test_stress() more similar to the test case by
looping over
w =
self.app.select_single(BuilderName='window_app').select_single('GtkButton',
label='gtk-quit')
but that also does not crash.
