[Bug 1068170] Re: ubiquity generates gtk_widget_get_preferred_width_for_height: assertion `height >= 0' failed errors

[Dmitrijs Ledkovs]

This is true, but I am not entirely sure which widgets it's actually
coming from and why.

I am suspecting it's the custom widgets we do for resize, which are not
even shown, but I have no way to confirm it. Furthermore those messages
are unhelpful since they don't give widget / GtkBuilder IDs although
realistically i should / can know about them.
