This is on Kubuntu 15.04, everything was working fine before upgrade. I can still access the camera from Dolphin by typing camera: or by using Digikam.

Is there supposed to be a udev rule for this? How does the notifier learn about new hardware?

I have exactly the same problem with Nikon Coolpix P50. Also Kubuntu 15.04

Have you found a solution for this?

I have same kind of problem with Canon Ixus 230 HS.
Dolphin does not show camera on the device list but I can access it with "camera:/"

No idea but the patches to https://bugs.kde.org/show_bug.cgi?id=336523 sound prone (notably given the original bug)
