Improved error reporting now reveals the Pythin traceback/stack trace:

The function "trysquash"

    def trysquash(vals):
        if len(vals)==1:
            try:
                vals = vals[0]
            except:
                pass
        return vals

is called from the line 401

400:        xvals = _eval('%s.%s;' % (idata_symb, axes_names[0]))
401:        xvals = trysquash(xvals)

which means that xvals is a float, not a list as expected...
