Both commands creates a new frame in Emacs-26 and Emacs-27. I have not 
tried 28 yet.

You may try if the following works for you (borrowed from 
`browse-url-xdg-open')

(let ((url "~/.bashrc"))
  (call-process "xdg-open" nil 0 nil url))

Such approach has an advantage: viewer remains running after exit from 
Emacs.

You may submit an emacs bug for `mailcap-view-file' that should have 
similar behavior.

P.S. I still believe that Emacs configuration for mailcap.el is broken 
if external handler is invoked from Emacs just to execute emacsclient. 
On the other hand it should not lead to Emacs crash.
