scripts defined by category not running?

[villain]

i have categories setup as follows;

category: tv
mode: +unpack
script: process-tv.sh
folder: completed
groups: various news groups

When I add a .nzb to the queue it is imported fine, and I can see the 'tv' assigned as the category, however the script is set to None. When the downlaoded is completed no script appears to have been run. if a processing script is assigned to the category should it be running, or do I need to assign the processing script to the nzb in the queue also?

If I manually assign the processing script to the nzb in the queue everything works fine

double and triple checked

the assigned script from the category never seems to run. if i assign the script to the queue item on the main screen, that works

im running 0.4.6

that seems to be for 0.5.x?
