Hi,
gobject-introspection can't build the typelib for enums like the following:

/**
 * GstDPVersion:
 * @GST_DP_VERSION_0_2: protocol version 0.2
 * @GST_DP_VERSION_1_0: protocol version 1.0
 *
 * The version of the GDP protocol being used.
 */
typedef enum {
  GST_DP_VERSION_0_2 = 1,
  GST_DP_VERSION_1_0,
} GstDPVersion;


Output is:
** ERROR **: Invalid typelib for module 'GstDataprotocol': In directory (Context: GstDPVersion)): The value is contains invalid characters: 0.2
aborting...
