Bug#904692: seahorse: Segfault few seconds after start

[Tobias Bengfort]

Package: seahorse
Version: 3.20.0-3.1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

I today noticed that seahorse crashes reliably about a second after it has been started.

I get the following output in the console:

   (seahorse:16130): Gtk-WARNING **: (/build/gtk+3.0-NmdvYo/gtk+3.0-3.22.11/./gtk/gtkicontheme.c:5493):gtk_icon_theme_lookup_by_gicon_for_scale: runtime check failed: ((flags & GTK_ICON_LOOKUP_GENERIC_FALLBACK) == 0)

   Segmentation fault

I know that seahorse has worked fine some time ago, but I am not sure when I last used it (could be few months).

Directly before trying to launch it I used python3-keyring. I cannot think of anything else that could be related.
