I believe it doesn't count as a bug, but when you're trying to get a key to the crypt just in the beginning of the game you can finish the quest for exp or steal the key. Also you can do both and get two keys. I still have one of the keys in my inventory after finishing the crypt quest. I was afraid that game might crash, so I didn't trash it.

Is it possible to make character use both keys when he enters the crypt? In the real world I would just drop the second key, because I know that the crypt will be open forever : )

You can trash the second key, the crypt remains open.

I know that it'll stay opened. I don't even need to go there anymore since I've finished larvae quest. But in my opinion it will make more sense if the character trashes the key himself.
