I don't understand why in your case the filesystem cannot be
read-only: AFAIK the way we uncompress files on the fly uses
temporary-file-directory, not the place where the compressed file
lives.

I'd start by looking at the value of temporary-file-directory, and if
that doesn't give any hints, step through the code in jka-compr to see
why it fails to uncompress the file.

Btw, does this happen in "emacs -Q"?  If not, some of your
customizations get in the way.
