Problems uploading new sources in nonfree

I'm not sure what's up but I've been trying to update the sources for one of my packages in nonfree and I keep getting 500 server errors. Does anyone know what's going on? If it helps, the package I'm trying to update is dolphin-emu. PS: Forgive my ignorance, but how do you respond to an thread in these mailing lists? It seems that when I try to do so, it creates a new thread instead.
