Example of the 

Trying to nest GtkExpanders causes the following error:

(gtk:XXXXX): Gdk-CRITICAL **: gdk_window_get_scale_factor: assertion 'GDK_IS_WINDOW (window)' failed

(xxxxx's are the process number afaik, could be wrong, changes everytime heh)

Attached is the example C source file. Was compiled with the following line:

gcc -Wall -g expander.c -o gtk `pkg-config --cflags gtk+-3.0` `pkg-config --libs gtk+-3.0`

This bug started occuring since 3.10, was not present in 3.8.6 or 3.8.7 from what I have been able to test. It did appear for me in 3.10.7

Error appears when expanding the first expander for me. Expected result should be not to generate the error.

Hope it helps
