GFX FIFO: Unknown opcode when dumping textures

[RagingFire]

I get the GFX Unknown opcode error when trying to dump textures in Fire emblem Path of Radiance. It occurs when the opening animation for the game begins to play. If I tell dolphin to ignore the error I get a warning box. The game continues to play at about 18 FPS and the screen starts to flash black throughout the animation.  Once I get past the opening it seems to play just fine, put I could try out doing more stuff. The game plays just fine when I'm not dumping textures (Aside from a small visual bug I saw recently that I could show too).

Anyway,
