The same issue can be triggered simply with

(let ((default-directory "/:/")) (process-file "true"))

Subject: [PATCH] Make process-file resolve the default directory

`call-process' doesn't respect file name handlers in
`default-directory', so `file-name-non-special' has to resolve them
for `process-file' (Bug#25959).

* lisp/files.el (file-name-non-special): Also resolve default directory
for 'process-file'.
* test/lisp/files-tests.el
(files-tests--file-name-non-special--process-files): Add unit test.

There are other functions which behave similar wrong:

M-: (start-file-process "foo" (current-buffer) "true")
M-: (shell-command "true")

Maybe you could add them here (not tested).

Best regards, Michael.
