I cannot import photos from a Nikon Coolpix P610 into Digikam 4.14.0 on Debian testing (stretch).
The log shown in console is:
digikam(7482)/digikam (core): Failed to detect camera with GPhoto2 from Solid information

It seems to be the same problem as discussed in https://bugs.launchpad.net/ubuntu/+source/digikam/+bug/865032 and #311393.

Actually, gPhoto2 2.5.9 does work with the camera (although it's not listed in `--list-cameras`), and I can use it's Fuse interface `gphotofs` to mount the camera folders. But I rather prefer to directly mount the SD card and import from it into Digikcam directly.

Reproducible: Always

Steps to Reproduce:
0. Launch Digikam from a console
1. Connect camera with USB cable
2. Click "Importation > Appareils photo > NIKON NIKON DSC COOLPIX P610"
3. Check the line displayed in the console

Actual Results:  
digikam(7482)/digikam (core): Failed to detect camera with GPhoto2 from Solid information

Expected Results:  
Nothing show in the console, and the actual importation window opened displaying photos from the camera.

At least, Digikam should warn the user about the problem (via a popup or notification message). Most users won't try to launch Digikam from Konsole to check for logs.
