I be want to say additional information. This bug is affected only if nm-applet used in KDE. In gnome, xfce this bug is not affected. I would not be so sure. Perhaps, it should be tested in different DE with GTK3 theme Oxygen-GTK3,- for example, in XFCE & GNOME 3. It seems to me that trouble is in the missing icon files somewhere at the path /usr/share/icons/* I would not be so sure.

I am able to reproduce the crash under KDE with your steps. Reloading of KDE is not necessary, just editing ~/.config/gtk-3.0/settings.ini and starting
nm-applet:
1. yum install oxygen-gtk3
2. put
[Settings]
gtk-theme-name = oxygen-gtk
into ~/.config/gtk-3.0/settings.ini
3. nm-applet
4. left click on the nm-applet icon (in the system tray) --> "Connect to
Hidden Wireless Network..."
5. nm-applet crashes
I've run the applet in gdb and found that the crash happens in gtkwidget.c:_gtk_widget_draw_internal().
Last two lines there are:
1) context = gtk_widget_get_style_context (widget);
2) _gtk_style_context_coalesce_animation_areas (context, widget);
But (1) return NULL and (2) crashes trying to access it.
The NULL is returned because the 'widget' has been freed before in g_emit_signal():

I'm not sure why the widget is freed, but it definitely depends on the oxygen theme. Having searched further, I discovered that line
-GtkComboBox-appears-as-list: 1;
in /usr/share/themes/oxygen-gtk/gtk-3.0/gtk.css causes the problem. If the line is removed or the value is changed to 0, the crash doesn't appear.
So, either there is a bug in glib/gtk theming or rather oxygen theme is at fault.

I'm moving the bug to gtk3 so that someone with the knowledge could look at the problem.
