Importing Imagecache presets via Features

Hi,
I'm experiencing some problems when importing imagecache presets via features. They all seem to be there when viewing the imagecache presets page - but aren't loaded into the actions/presets imagecache tables (perhaps that's normal?). Then they don't actually have the proper effect on images.

I'm using:
Features 1.0
Imagecache 2.x-dev latest tarball
Pressflow core (based on 6.19)
PHP 5.3

Along with these imagecache action modules:
smartcrop
imagecrop (javascript_crop action)

Also, the javascript_crop action works fine on the imported feature - but doesn't save properly because in the 'imagecrop' table it saves the record with a presetid of 0 - presumably because it can't identify the presetid of the imagecache preset its editing.

I'm not quite sure where the issue lies - with the action modules, with the imagecache import/export, or with how features handles the import/export - and I'd appreciate any guidance for troubleshooting please.

My hunch is that smartcrop and imagecrop simply don't support having imagecache presets and actions in code and are directly going to the DB to look for information rather than using the imagecache API. But is it right that imagecache doesn't populate the imagecache_actions and imagecache_preset tables with the data import from the Feature?

Thanks very much
Steve
