I have no doubt that you (or some code in Emacs) somehow caused the
shell output buffer to be displayed in the minibuffer.  Emacs refuses
to kill such buffers, and that's what you see.

If there's a bug that causes this, it has done its thing long ago, and
our chances to hunt it down given your situation are pretty much nil.

Thanks.
