Gtk:ERROR:../../../../gtk/gtkpathbar.c:1342:set_button_image_get_info_cb: assertion failed: (cancellable == data->button_data->cancellable) Aborted (core dumped)

Expected behaviour

There shouldn't be a crash when clicking the custom component.

Steps to reproduce

To reproduce it delete any settings.json and any "BitcoinCore-App*.conf" in home/.config/BitcoinCore
