I can't duplicate this message, though I am using a different environment (Kivy 1.9.1, Python 3.4.4, Windows 10). It looks like it may have to do with kivy, though I am not sure. However I do get error messages, though they are only in console and do not cause any crash.

I receive several of the following:

Traceback (most recent call last):
  File "kivy\properties.pyx", line 501, in kivy.properties.Property.dispatch (kivy\properties.c:6557)
  File "kivy\_event.pyx", line 1224, in kivy._event.EventObservers.dispatch (kivy\_event.c:13497)

    'Too many children in GridLayout. Increase rows/cols!')
kivy.uix.gridlayout.GridLayoutException: Too many children in GridLayout. Increase rows/cols!

I expected the Kivy Designer "KV Lang Area" or Error console to report this as an error or warning, however no such message appears. The widget in the area still appears to be a child of the GridLayout, but only the positioning (bottom left corner) states otherwise.
