Do you think the two events are actually related? I'm trying to think how the fact that the tank is empty would cause debris to come out... or where ever it came from.

I think the number one reason to not let the tank run completely empty is that you can get it refilled on your terms, not when the damn tank decides to go empty. Unless you always have a backup tank, then it doesn't matter.
