The bug appears to be caused by a memory allocation or reference-count
error. I've built network-manager-applet (aka package network-manager-
applet) and added a report:
src/wsp-wpa-eap.c::wso_wpa_eap_new()
phase2_type_combo = glade_xml_get_widget (opt->uixml,
"wpa_eap_phase2_type_combo");
tree_model = wso_wpa_create_phase2_type_model (capabilities, TRUE,
&num_added);
printf("About to call GTK_IS_TREE_MODEL(%lX)\n", tree_model);
printf("GTK_IS_TREE_MODEL (%lX)=%d\n", tree_model,
GTK_IS_TREE_MODEL(tree_model));
gtk_combo_box_set_model (GTK_COMBO_BOX (phase2_type_combo), tree_model);
gtk_tree_model_get_iter_first (tree_model, &iter);
gtk_combo_box_set_active_iter (GTK_COMBO_BOX (phase2_type_combo),
&iter);
Mostly it will crash, but sometimes it will work okay. Each of the
following was generated by starting nm-applet, clicking the
notification-area icon, and choosing "Connect to Other Wireless
Network..." :
$ nm-applet
