Comment:

 strk: Yes upgrading to the GEOS trunk fixes it.

 For others who want to try this:

 1. Download the trunk from http://geos.osgeo.org/snapshots/
 2. tar -xvfj the file
 3. configure, make, sudo make install
 4. Remove the existing libgeos-3.2.2.so, libgeos_c.so, libgeos_c.so.1
 files from /usr/lib, replace with libgeos-3.3.0.so, libgeos_c.so, and
 libgeos_c.so.1 files from /usr/local/lib.
 5. Restart postgresql.
 6. Verify you now are using GEOS 3.3.0 by running "SELECT
 postgis_full_version()".
