You make a very good point here. We are rethinking the Manager concept. Perhaps something like this: * Each specialized thumbnailer makes itself activatable by installing a .service file * A directory with mime-type.service files that contain a string like: com.adobe.thumbnailer (for example for application/pdf) The thumbnailer will simply try to fopen() the mime-type.service file, if it fails it'll try to use an internal method to thumbnail, if that fails it can't thumbnail. If the fopen() succeeds, it reads the string and calls [string].Create() to request the creation of the thumbnail. If the specialized thumbnailer is not running, it'll be activated by DBus. We simply get rid of org.freedesktop.Thumbnailer.Manager How does that sound? > Also I'm not entirely convinced using DBus messages for managing such > register plays too well with package management (packages installed as > root, thumbnailer running as user?)
