[gnome-db] GdaNumeric problems

[Murray Cumming <murrayc murrayc com>]

When using the Python gi.repository.Gda API, I'm seeing some nonsense
strings in the Gda's Numeric.number field. This valgrind warning shows
that something is wrong at that point. I suspect that the whole
GdaNumeric has already been freed. I got the Numeric from a call to
datamodel.get_value_at().

Does anyone have any idea what might be wrong?
