The second time I've applied your patch it works. I get a similar
result. Don't ask me what happened before, pilot error very likely.

Same error here. The backtrace shows me:

  tramp-file-name-handler(insert-directory "/ssh:localhost:/home/albinus/src/emacs/src/*/gray*" "--dired -al" t nil)

I believe it is wrong to expand wilcards in `insert-directory'. It is
not designed for that. Expanding must happen in
`dired-insert-directory', which calls then `insert-directory' for the
results.

This relates to your description in etc/NEWS:

*** Dired supports wildcards in the directory part of the file names.

Best regards, Michael.
