Description of problem:
Whenever I try to edit the name field of the preset stations, I get a FATAL CRASH.

The following error message is echoed to standard output:
gnomeradio-ERROR **: file prefs.c: line 417 (name_cell_edited_cb): assertion
failed: (mom_ps < g_list_length(menuitems))

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

Also, not sure if it is related but at startup (before any crash or anything), I
get the following error message echoed to stdout:
(process:11905): GStreamer-WARNING **: The GStreamer function
gst_init_get_option_group() was
        called, but the GLib threading system has not been initialised
        yet, something that must happen before any other GLib function
        is called. The application needs to be fixed so that it calls
           if (!g_thread_supported ()) g_thread_init(NULL);
        as very first thing in its main() function. Please file a bug
        against this application.

Note that the radio itself seems to work fine until I try to set the name field
in the presets.

How reproducible: 100%
- Start gnomeradio
- Go into "Gnomeradio Settings"
- Type something in the name field of one of the presets (create one if none
existig)
- Press close
- CRASH
