Fails for Emacs 23, but not for Emacs 22 or Emacs 23 run with -nw.

I can't reproduce this anymore, so presumably this old bug is fixed.
Juri, could you confirm?

I still can reproduce this bug on the newest Ubuntu version 10.10 and
GNU Emacs (x86_64-pc-linux-gnu, GTK+ Version 2.22.0) of 2010-10-22

Your shell ignores SIGPIPE for interactive sessions. Gzip checks if SIGPIPE is ignored, and if it is not, installs a signal handler that prints "gzip: stdout: Broken pipe". Try
M-! bash -i -c 'locale -m' RET

That gives some job and terminal control errors from the shell, but no gzip messages. I don't know if ignoring SIGPIPE for subprocesses is the right thing for Emacs to do.
