projectile-kill-buffers tries to reopen old TRAMP buffers

Hello,

If I:

* open some files over TRAMP
* kill the buffer/file
* kill all the TRAMP buffers
* naviguate to another project, and open a file there
* do `C-c p k`

The minibuffer shows me that it reopens previous TRAMP connection, eventually decides it's not useful for the buffer lists and behaves properly and asks me if I want to kill the buffers for the current project... but the TRAMP part looks really useless.

Any idea what could trigger this? I assume `projectile-kill-buffers` would be pretty stupid and just iterate over the buffers and check with `projectile-project-root`? I recently discovered ido/recentf was pretty lame reguarding cache when TRAMP was involved, maybe it has something to do with it.

If you have no idea I'll probably investiguate.
