gnome-shell-extension-prefs crashed with SIGSEGV in gtk_container_real_check_resize()

[Rachel Greenham]

It was a bit delayed but I think this probably relates to extension gnome-display-switcher, which is probably in need of an update. The configuration dialogue was failing to open either from the extensions site or the tweak-tool extensions tab... then this error appeared.

I can't find any other crashes that look like this. Is it still happening?
