No, I don't think the debugging information is there. In the backtrace
you sent me, you'll notice that functions in lilypond show their
arguments:

#19 0x08214a91 in Score::book_rendering (this=0x84e5538, layoutbook=0x859e220,
    default_def=0x8575248) at /home/fede/lilypond-master/lily/score.cc:160

while functions from guile just show an empty pair of parentheses
(even when the function takes some arguments):

#13 0xb7f2a9f1 in scm_call_1 () from /usr/lib/libguile.so.17

If the debugging information were installed, there would be more
information inside the (). Since Debian doesn't seem to have a package
for it, the easiest way to get debugging information may be to compile
guile yourself. If you install it in /usr/local (which should be the
default) and you ensure that /usr/local/bin precedes /usr/bin in your
PATH, then re-./configure lilypond and rebuild so that it will use the
new guile.

Cheers,
Joe
