Usage of detectclipping

Hi all.

I'm working on a project where I'm trying to get detectclipping to work.
I'm not 100% how the filter work, but I've been trying to get the gui
configuration to work but I keep getting a segfault.

I tried adding the detectclipping filter after PRE and POST in Filters
and Preview menu.

Filter is enabled and I've tried run as POST filter and without.
I've even tried logging the values to a file.

The log file contains :

Command exits with failure code:
Command: mkdir -m 0775 -p
'/home/media/dvdrip-data/the_thirteenth_floor/tmp' && cd
/home/media/dvdrip-data/the_thirteenth_floor/tmp && mkdir -p
/home/media/dvdrip-data/the_thirteenth_floor/avi/002 && execflow -n 19
transcode -H 10 -a 0 -x vob -i

--progress_rate 25 -J detectclipping=range=0-4294967295/1:limit=24 &&
echo EXECFLOW_OK

Output: pe

Any Ideas what I'm doing wrong ?
