I merged gphoto2, unmerged kdegraphics, merged kdegraphics. went into kcontrol->perhiperals, and i could not find kamera. I think that's where it is supposed to be, but it was nowhere to be found.
Which profile do you use? Is gphoto2 in your USE-var?
should be fixed now (added gphoto2 to auto-use). please try, if it still does not work, reopen this bug.
