It is trying to create a copy of the thing you are trying to put into the cell 
but fails somehow.

Maybe this change is enough:
      gtk_clist_set_text (GTK_CLIST (add_file_list), row, 1,
                           g_strdup(filelist[j]->d_name) );

I suspect (really not sure!!!) that this might help. (It might be you get no
more coredumps but the labels are all the same or empty...dunno)
 
If not try to make char *filelist available for all the C code. I think the
point is to make a copy somewhere, as this is referred to in drawing/accessing
etc., and as the function declaration says must be some const gchar *text like
in gtkclist.h:

void gtk_clist_set_text (GtkCList    *clist,
			 gint         row,
			 gint         column,
			 const gchar *text);

To say it in other words: You have to pass a pointer in this *text field,
which does not only have filescope but must be readable from the function
containing the callback. Maybe g_strdup can do this also.

    hope that helps!
