G-Wrap also has been bitten by that; from the guile-1.8 changelog.Debian:

guile-1.8 (1.8.2+1-2) unstable; urgency=low

  * Re-enable threads.

Apparently, enabling thread support changes the ABI; to verify this is
indeed the problem, try texmacs together with guile-1.8 1.8.2+1-1 - if
I'm correct, that should fix the segfault. Then just rebuild with the
latest guile-1.8 to fix the problem.
