Yes, but please can you read Kevin's comment (comment #74) about this
segfaults. He compared this bug with K3b's segfault on exit. 
So, maybe this segfault isn't MLT's bug, but ffmpeg's...

Hmm, I found this in makefile

======================================
include ../../../config.mak

TARGET = ../libmltmotion_est.so

OBJS = factory.o \
           filter_motion_est.o \
           filter_crop_detect.o \
           filter_autotrack_rectangle.o \
           arrow_code.o \
           filter_vismv.o \
           producer_slowmotion.o

CFLAGS += -I../.. 
------------------------------------
LDFLAGS += -L../../framework -lmlt
------------------------------------
SRCS := $(OBJS:.o=.c)

all:    $(TARGET)
=======================================

LDFLAGS has -lmlt option enabled for this library, or I'm seeing something
completely wrong, or -lmlt and -lm isn't same (I think that's -lmlt is the same
as -lm -lt)?!

In configure exist this option:
=============================================================================
--arch='arch'           - Compile for a specific architecture (default: none)
=============================================================================
Maybe this can help, but I'll ask upstream ;)

I'll ask, too.

Thanks for your returning to review :)
