[D33r-Gee]

Is there an existing issue for this?

• I have searched the existing issues

Current behaviour

with #408 when clicking the custom button here it causes a crash:
Gtk:ERROR:../../../../gtk/gtkpathbar.c:1342:set_button_image_get_info_cb: assertion failed: (cancellable == data->button_data->cancellable) Bail out! 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

Also, it happens without deleting anything.

I've been trying and I'm not able to reproduce this. Any information on the OS and DesktopManager (Gnome/KDE?) that is being used?

[MarnixCroes]

for me it's Ubuntu 22.04.4 LTS, GNOME version 42.9

FYI,
on commit 8d53c44
it sometimes throws this in terminal when clicking on the Custom button (no crash)
(bitcoin-qt:460568): Gtk-CRITICAL **: 19:57:07.987: gtk_image_set_from_gicon: assertion 'GTK_IS_IMAGE (image)' failed.

which is new, it didn't happen before.
