tree store gtk warning

[Stefan Kost <kost imn htwk-leipzig de>]

hi hi,

I trying to resolve this since two days now and I must admit - I don't see it.

Thats the message I receve switching to the tab the tree-view is on and below is
the gdb stacktrace.

Gtk-CRITICAL **: file gtkliststore.c: line 569 (gtk_list_store_get_value):
assertion `column < GTK_LIST_STORE (tree_model)->n_columns' failed
aborting...

Program received signal SIGABRT, Aborted.

Previous frame inner to this frame (corrupt stack?)

Here is the source (it maight take an hour or two before sf.net refreshes the
page to reflect the last-commit):
http://cvs.sourceforge.net/viewcvs.py/buzztard/buzztard/src/ui/edit/main-page-sequence.c?view=markup

And here is an excerpt of the essential part:

col_ct=(SEQUENCE_TABLE_PRE_CT+track_ct);
store_types=(GType *)g_new(GType *,col_ct);
// for background color columns
store_types[SEQUENCE_TABLE_SOURCE_BG   ]=GDK_TYPE_COLOR;
store_types[SEQUENCE_TABLE_PROCESSOR_BG]=GDK_TYPE_COLOR;
store_types[SEQUENCE_TABLE_SINK_BG     ]=GDK_TYPE_COLOR;
// for static display columns
store_types[SEQUENCE_TABLE_POS         ]=G_TYPE_LONG;
// for track display columns
for(i=SEQUENCE_TABLE_LABEL;i<col_ct;i++) {
  store_types[i]=G_TYPE_STRING;
}
store=gtk_list_store_newv(col_ct,store_types);
g_free(store_types);

for(i=0;i<rows;i++) {
  gtk_list_store_append(store, &tree_iter);
  for(j=0;j<track_ct;j++) {
    ...
    gtk_list_store_set(store,&tree_iter,SEQUENCE_TABLE_PRE_CT+j,str,-1);
  }
}
gtk_tree_view_set_model(self->priv->sequence_table,store);
for(j=0;j<track_ct;j++) {
  renderer=gtk_cell_renderer_text_new();
  g_object_set(G_OBJECT(renderer),"editable",TRUE,NULL);
  gtk_tree_view_insert_column_with_attributes(
    self->priv->sequence_table,-1,NULL,renderer,
    "text",SEQUENCE_TABLE_PRE_CT+j,
    NULL);
}

Any help is hightly appreciated. Should those messages trigger a bit earier (on
creation time).

Ciao
  Stefan
