This puzzles me is that the symbold db, in the compilation unit
babl_type.c (defined in babl-internal.h which it is included from). Is
0x0 at this stage, it should not, since it should be initialized by
babl_type_init, called from babl_init() in babl.c before it reached
babl_extension_init ().
:/
Your previous babl backtrace was due to the format with premultiplied
floating point linear RGB with alpha format was not found by the name
"RaGaBaA float", which is what GEGL references this format as, this name
is registered later by one of the extensions to babl. (I get the same
error if I temporarily remove the extensions from
/usr/local/lib/babl-0.0/).

Which makes it strange that changing it,. changed the behavior of the
program.
