Can you show a recipe, preferably starting from "emacs -Q"?  Or at
least explain how you get to this *mailcap shell* buffer?  That would
help us investigate the issue.

A stab in the dark: if the buffer's name is actually " *mailcap shell*",
i.e. it begins with a space, then you can switch to it by typing its
name at the "C-x b" prompt.
