problem saving history

[Karol . Skocik]

Hi guys,
  I have a problem which is driving me nuts and can't find anything
with google. When I edit some file or work in Slime REPL and close
emacs, I get this error:

"Wrong type argument: stringp, \\.\\.\\." while saving history

I was trying to locate which variable (or something else) holds the
location of history file (or does it work in completely different
way?) but my emacs-lisp-fu equals to almost zero.

I have emacs 22.1/gentoo x64.

Can some good soul give me some advice?

Thank you!

Karol
