emacs 24.3, guile 2.0.9, geiser 0.4 (from elpa).

I'm evaluating regions from a file with many functions (C-c C-r). Even
with a clean guile instance (only with the definitions above) trace
produces no output. Loading the file directly into guile or cutting and
pasting the definitions to it works as expected. On my .emacs [1], I
have the following:

(setq geiser-repl-history-filename "~/.emacs.d/geiser-history")
(setq geiser-repl-query-on-kill-p nil)
(setq geiser-repl-query-on-exit-p t)
