Device manager actions

SUSE 11.3 KDE 4.4.4 - Can somebody point me to a howto so I can edit the actions performed. I just bought a new camera and it only allows me to download with digiKam. Formerly, it would allow opening it with my file manager. Trying System Settings > Device Actions tells me “Cannot be deleted”. The edit options such as “content disjunction” are very confusing to me, not being a native English speaker.

Thanks.
