Works for me starting from emacs -Q.

This looks like a dup of #528. I suspect there might be some settings that are needed to trigger this, but so far nobody has managed to explain what they are and I have never managed to trigger it myself.

[zzgraph]

It happened to me too. But it was caused by a package installed parallel.
I think this always happens when someone installs 2 parallel versions, especially when there's a yasnippet-bundle 0.6.1 on marmalade repo which may cause confusion.

@zzgraph Yep. The yasnippet-bundle was the source of my woe. Thanks!
