 I thought I had reported this before and I had fixed it in my local copy,
 but I cannot find the ticket.

 The Balloon activity has a broken icon svg file which is causing the
 append_item method in combobox.py to throw an exception and prevent Sugar
 from launching properly.

 pseudo patch:
 lines 116-117

 -    pixbuf = gtk.gdk.pixbuf_new_from_file_at_size(
 -        file_name, width, height)

 +    try:
 +        pixbuf = gtk.gdk.pixbuf_new_from_file_at_size(
 +                    file_name, width, height)
 +    except:
 +        pixbuf = None

 This happened when I installed the latest update to Sugar which apparently
 overwrote the patch I had applied earlier.
