In a network containing devices with both GVRP and MSTP enabled, GVRP packets are forwarded along the CIST. In this case, if you want to broadcast packets of a specific VLAN through GVRP, be sure to map the VLAN to the CIST when configuring the MSTP VLAN mapping table (the CIST of a network is spanning tree instance 0).
