Hello,
if it is of any help, the bytes from the kernel message
point to following line:


https://sources.debian.org/src/libnma/1.10.6-1/src/nma-cert-chooser-button.c#L116

116 	model = GTK_LIST_STORE (gtk_combo_box_get_model (GTK_COMBO_BOX (priv->button)));


A more complete backtrace would probably get visible
in journal by installing the package systemd-coredump.

Kind regards,
Bernhard
