You could instrument 'emacsclient' to produce a stack trace, with an
option analogous to --debug-init. It would be useful for future bugs
as well. "Wrong type argument" is better than nothing, but we agree
that it's not very useful.

Both myself and the other reporter seem to have noticed the problem
appearing in Emacs 25. Actually for me, an Arch Linux user, looking at
the dates in /var/cache/pacman/pkg I think the problem may have
occurred after emacs-25.1-4-x86_64.pkg.tar.xz (installed Feb 7) since
the previous patch level 25.1-3 was installed Dec 24 2016 and I don't
remember any crashes so long ago. But Joseph's original report is 9
months old. I have of course made changes to ~/.emacs in this time but
I have very little idea what of that code is run by emacsclient. It
seems likely that the problem stems from a change that was made to
Emacs, and we have a record of such changes, so it may be useful to
check that record.

Thanks for your reply.
