Bug

Hi, Espen

I'm learning my way through clg. It seems I have found a bug in the 
tree-view-row-data method. On invocation it gives this error:

Gtk: gtk_list_store_get_value: assertion `column < 
list_store->n_columns' failed
    [Condition of type GLIB:CRITICAL-LOG-LEVEL]

Restarts:
   0: [CONTINUE] Return from callback function
   1: [RE-INVOKE] Re-invoke callback function
   2: [ABORT] Disconnect and exit signal handler
   3: [ABORT] Exit debugger, returning to top level.

Backtrace:
   0: (NIL 5990772437936 5990772437935 #<FUNCTION GLIB::LOG-HANDLER>)
   1: ("foreign function: #x41E152")
   2: ("foreign function: #x4177E2")
   3: ("foreign function: #x40001225")

It was iterating over list_store->n_columns + 1 columns, so fixed it and 
the error is gone.

Here is the diff:

Could you please confirm if it is a bug and apply the changes?

Thank you for making clg available.
