No further comments here, and I think the conclusion was that this is
not a bug in Emacs.  I'm therefore closing this bug report.

Dear Emacs developers, this happened when I tried to
open a file via emacsclient via a convoluted stack of
shell scripts.  I am sadly not able to reproduce.
Perhaps the backtrace below helps.
