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/*
carasin, thanks for the reproducer in the description! 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(): (gdb) s _gtk_widget_draw_internal (clip_to_size=1, cr=0x3c1f8a7860, widget=0x10307e0 [GtkToggleButton]) at gtkwidget.c:5722 5722 g_signal_emit (widget, widget_signals[DRAW], (gdb) p widget $1 = 0x10307e0 [GtkToggleButton] (gdb) p *widget $2 = {parent_instance = {g_type_instance = {g_class = 0x1048c10}, ref_count = 2, qdata = 0x0}, priv = 0x1030820} (gdb) watch *0x10307e0 Hardware watchpoint 4: *0x10307e0 (gdb) c Continuing.

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.

Jirka Klimes, thanks for your work and workaround. Awaiting the further solution to this problem.
