Okay, interesting. Well, at least you made it work.
I uploaded a patch for the Galv Layers Support (0.9). Can you please re-download and include both MK_Minimap and MK_Minimap_GalvLayerSupport?
Also, verify that you registered Galv Layers in Plugin Manager --> MK_Minimap_GalvLayerSupport. Keep in mind that only static layers are supported right now.
