Yes, never call g_free() on an object!

There is a bug in the gda_column_index_finalize() function: there is a
g_free() there wich does it all... If you remove that line, then I'll
be fine.
Here is the patch attached (which also corrects another potention
problem). I'll commit the patch to CVS tonight.
