The problem is easily fixed by changing the code as follows:

GFitsBinTable GModelSpectralTable::create_spec_table(void) const
{
    // Compute number of rows
    int nrows = 0;
    if (m_spectra.dim() > 0) {
        nrows = 1;
        for (int i = 0; i < m_spectra.dim()-1; ++i) {
            nrows *= m_spectra.shape()[i];
        }
    }
This results in
$ python
>>> import gammalib
>>> spectrum=gammalib.GModelSpectralTable()
>>> spectrum.save('spectrum.fits')
>>> ^D
