 This is similar to #2108

 When I run below on:

 {{{
 SELECT postgis_full_version() || ' ' || version();
 POSTGIS="2.1.2 r12389" GEOS="3.4.2-CAPI-1.8.2 r3924" PROJ="Rel. 4.8.0, 6
 March 2012" GDAL="GDAL 1.10.0, released 2013/04/24" LIBXML="2.7.8"
 LIBJSON="UNKNOWN" RASTER PostgreSQL 9.3.4, compiled by Visual C++ build
 1600, 64-bit

 }}}



 {{{
 SELECT ST_Segmentize('LINESTRING EMPTY'::geometry, 0.5);
 }}}

 I get


 {{{
 ERROR:  getPoint4d_p: point offset out of range
 }}}

 Would seem to me that this should just return back a LINESTRING EMPTY.

 Someone complained about a similar issue here:
 http://gis.stackexchange.com/questions/92552/postgis-error-getpoint4d-p
 -point-offset-out-of-range

 Though I wasn't able to replicate the issue with his data.  I will retry
 again.
