Comment(by strk):

 I can't confirm that geometry triggers an error
 inST_SimplifyPreserveTopology:
 {{{
 with inp as ( select
 '0102000020BB0B00000C00000059FFFFCAC03F39412A008004CBFC51415BFFFF61B53F39412B00809DCBFC51415BFFFF40AE3F39412B00005DCEFC51415AFFFF4FB43F39412B0080DFD0FC514159FF7F29A13F39412A000028DBFC51415AFF7F88A23F39412B008014E0FC51415BFFFF21AC3F39412B0000EFE0FC514159FFFFF3C53F39412A008018D6FC51415AFFFF80DA3F39412A0080ECD2FC51415BFFFFA1DF3F39412B000022CEFC51415AFFFFF3D33F39412A0080DFCCFC514159FFFFCAC03F39412A008004CBFC5141'::geometry
 as g ) select st_isvalid(st_simplifypreservetopology(g, 500)) from inp;
 }}}

 Does the above query return false for you ?
 I thought in IRC you said a similar query was returning false (ie: non-
 valid returns from ST_SimplifyPreserveTopology)
