Quoting a quote seems to be broken.
Edit to add: Trying to reproduce this and I can't I wonder if it has been replying to broken messages. Or perhaps it only sometimes happens.
If I quote someone in a post, I find I have to go back and edit the message. At first I thought I had done something stupid (Problem between keyboard and screen ;) ) but am convinced not that something is broken. Have seen other people's posts looking the same. Basically, if quoting someone who has quoted someone, the wrong person gets attributed and some garbage text turns up which is the correct quote open string.

My reply with quote of that one needed manual editing to get it right.
