Function ST_InterpolatePoint doesn't work with LINESTRINGM

Description

Hi to all,

If I execute this query 

 SELECT ST_InterpolatePoint(geom,ST_Transform(ST_SetSRID(ST_MakePoint(-3.17287857984195,40.7322588249179),4326),3042))
 FROM roads as rc
 WHERE idvia = '666XX';

The result is 

ERROR:  ST_InterpolatePoint: 1st argument isn't a line


********** Error **********

ERROR: ST_InterpolatePoint: 1st argument isn't a line
SQL state: XX000

Is there a way to workaround and transform MULTILINESTRINGM to LINESTRINGM without loosing the measure?

Thanks a lot

Sure, ST_Dump should convert multis to singletons w/o dropping dimensions.
