| Typing "camera:/" in Dolphin gives "Invalid protocol" but it gives access to the camera and its photos in Konqueror, with a PTP camera. 
 If I try to copy and paste a picture from Konqueror into Dolphin, it fails and Dolphin reports "Could not start process Unable to create io-slave: klauncher said: Unknown protocol 'camera'" although this works fine between Konqueror tabs.
