For me this took place after an ordinary login without manually mounting the directory. Since then I've used ecryptfs-recover-private to mount it privately so I could copy out as much data as I could to some other directory (it, too, sees the corrupted filesystem with duplicate directories and the like).
I just went into ...home/.ecryptfs/myname and did an ls -laF .Private/ and was surprised to see both encrypted and unencrypted names of the duplicated files and directories!

I'm not familiar enough with ecryptfs to know for sure, but that doesn't smell right to me.
