bug#2563: rgrep killing emacs

[alex]

Hello,

I am running this verison of emacs:

GNU Emacs 23.0.91.1 (i686-pc-linux-gnu, GTK+ Version 2.12.11) of 
2009-03-02 on avk

On Gentoo Linux.

I think there is problem with process management. I have found this bug:

1. Run rgrep (some long like finding some text in homedir)
2. Run rgrep again (previous is not finished)
3. rgrep asks: "A grep process is running; kill it? (y or n)". If I answer
   yes,
   Fatal error (6)zsh: abort (core dumped)  emacs -Q -nw
