Well, if it wasn't a bug it certainly was suprising behaviour. It also
seems to violate the stdlib documentation. Since it's such a basic 
operation it took me a while to track down what was going on...

Erlang (BEAM) emulator version 4.9.1 [source]

Eshell V4.9.1  (abort with ^G)
1> []++[1].
2> []++{1}.

At least it's simple to demonstrate. Apologies if this has been
fixed in the most current.
