So basically...
After Mannimarco was defeated, the chamber was flooded by an endless stream of ghosts, causing a big fps drop in the process. The cutscene between Mannimarco and Molag Bal played out as this occurred and the quest continued just fine after the swarm/lag killed me.

It's been a while since I did this quest, and I'm pretty sure this didn't happen last time.
