When starting SVN GTK2 Wireshark on my Fedora system (see below for version
info), I get two of the following messages.

(lt-wireshark:11754): GLib-GObject-CRITICAL **: g_value_get_pointer: assertion
`G_VALUE_HOLDS_POINTER (value)' failed

--------------

A little debugging shows that the messages are emitted during the call to
gtk_container_add() in add_byte_tab() (packet_panes.c)


    g_object_set_data(G_OBJECT(byte_view),E_BYTE_VIEW_TVBUFF_KEY, tvb);
>>  gtk_container_add(GTK_CONTAINER(byte_scrollw), byte_view);
    g_signal_connect(byte_view, "show",
                     G_CALLBACK(byte_view_realize_cb), NULL);

---------------

backtrace just after call to gtk_container_add() (and after messages emmitted).

#0  add_byte_tab (byte_nb=0x8d88030, name=0x81f00cd "",    tvb=0x0, tree=0x0,
       tree_view=0x0) at packet_panes.c:477

#1  0x080b097d in byte_view_new () at packet_panes.c:436

#2  0x080a4717 in create_main_window (pl_size=280, tv_size=95, bv_size=75,
       prefs_p=0x828cf20) at main.c:3792

#3  0x080a326a in main (argc=0,    argv=0xbffff148) at main.c:2987


If any further debug info is needed, please let me know

(Note: I don't see these messages when starting GTK3 Wireshark)
