Standard Emacs settings (csf.el) break grep buffer in Emacs 22.1.1 on Mandriva 2008

1. Login to Linux workstation running Mandriva 2008 with Emacs 22.1.1 (e.g.
mirex -- tested both locally and remotely -- with TurboVNC)
2. Start emacs (by "emacs &" -- tested under user "det")
3. Run grep by pressing M-X (Esc-X if logged remotely), then "grep" and Enter
4. Define some reasonable arguments, e.g. "shell [user path removed]/sun/*.el" and press
Enter
5. Check output -- it contains unprintable symbols like:
     [user path removed]/sun/det-common-def.el:105:
        (load-file (concat det-el-path "/det-shell.el"))
   instead of
     [user path removed]/sun/det-common-def.el:105:
        (load-file (concat det-el-path "/det-shell.el"))

The problem is caused by some setting done while loading csf.el (taken by
default from [user path removed]/emacs). Everything seems to work well if csf.el is
not loaded; thus the question is whether it is needed at all?
