Let me start with steps to reproduce: - launch gnome-control-center, - click on users applet, - unlock the thing, - click [+] to try to add an user. This happens, with a segmentation fault. (gnome-control-center:30279): Gtk-CRITICAL **: gtk_toggle_button_get_active: assertion `GTK_IS_TOGGLE_BUTTON (toggle_button)' failed (gnome-control-center:30279): Gtk-CRITICAL **: gtk_bin_get_child: assertion `GTK_IS_BIN (bin)' failed The problem is with the Gentoo patch gnome-control-center-3.5.91-optional-kerberos.patch. The bug occurs in panels/user-accounts/um-account-dialog.c, in function mode_change. Let's assume kerberos disabled (if it's not, the bug should not occur). Because NUM_MODES = 2, the loop executes two times. However the second time it executes, button = NULL. And it's the culprit. It's NULL (and perhaps other elements related to blah[UM_ENTERPRISE == 2] are too), because: around line 1024, stuffs like 'self->mode_areas[UM_ENTERPRISE] = widget' are excluded because of the #ifdef KERBEROS, so it's not set, so it's NULL. I'm attaching a patch that should be attached on top of the current patch that fixes it. However, you may want to take a second look, and maybe also correct the patch submitted upstream. Without the Gentoo patch it works. Regarding "maybe broken handling of kerberos USE flag": it shouldn't happen if USE=kerberos is on, unless something else is bad in the patch, but it does. So maybe the flag has no effect - but it needs to be checked. But if I compiled g-c-center without the 'epatch … kerberos…patch' part, I got a different 'add user' dialog. Reproducible: Always

Confirmed; thanks for reporting. We should review the optional-kerberos patch to make sure there aren't other similar problems with it.
Regarding bug title change: to be clear, I've experienced it with the kerberos flag enabled, not disabled (the flag handling seems broken here). However the crash probably occurs with 'kerberos' disabled too. Thanks for looking into it.
