[Bug 503455] Re: Digikam slow to scan camera (regression)

[Reuben Firmin]

It's 10 times slower, easily, when scanning the camera for images. I
plug in the camera, digikam pops up, opens the camera import dialog, and
then just sits there for 20 seconds before even rendering thumbnails.
Each thumbnail from that point on takes maybe 1s to render. Previously,
this was extremely fast.

I had to install gphoto2; it wasn't present before.


I can't do the test of running digikam from the command line, as it fails to recognize the camera. It only works when I plug the camera in.
