Version:           4.5 (using KDE 4.5.5) 
OS:                Linux

I can connect to my PTP camera (Canon PowerShot A720 IS) via camera:/
protocol in Dolphin or Krusader only as root. The problem seems to be as
some privileges, but: as common user I see the camera (via lsussb),
Digikam operates OK, gphoto2 too...

Reproducible: Always

Steps to Reproduce:
Login to KDE as common user, connect camera to PC, start Dolphin or Krusader, 
type camera:/ into address line, press enter (or any similar process, eg. via 
bookmarks)

Actual Results:  
Blank (empty) window in Dolphin or Krusader.

Expected Results:  
Window with proper file and folder structure from camera.

The process described above works correctly in root mode of Dolphin or
Krusader, or in root system session (login to KDE as root). I observe
continuos problem with camera:/ protocol in KDE 4.x.y - this protocol
worked without problem in KDE 3.5.x. There was no function in KDE 4.5.4
and earlier (either as common user, or as root)....

The "workaround" is to use Digikam, but I don't want to do it - I prefer
working with photos as files in suitable file manager. Why not, after
all, if there is a "camera:/" protocol, isn't it so?

Konqueror uses the Dolphin filemanagement part to display the list of

I don't have the slightest idea what that message means, and I don't
have a clue either what Dolphin might be doing wrong here.

I'd appreciate it if the camera people could provide some more
information about this message and possible causes of this bug.

I did some fixes since 2010 to the kio slave that probably avoiid the
error 150, but I cannot say for sure.

Thanks for the info, Marcus!

@everyone who can reproduce this bug: does accessing the camera work for
you in Digikam?

BTW, accessing the pictures in my camera using "camera:/" works nicely
here in KDE 4.10 as provided by Opensuse.

First make sure you have /usr/lib/kde4/kio_kamera.so installed (it's in

If there are still problems, make sure that the USB device under

I may be experiencing this bug under Debian testing's KDE 4.11.3.

When I plug my Canon PowerShot, Device Notifier offers me 3 actions,
opening in Digikam, Gwenview or Dolphin. I noticed something was wrong
when Dolphin showed my home directory rather than the camera's content.
I can reproduce by entering "camera:/" in KRunner. There is no error,
just an incorrect. However, Gwenview uses a camera:/ URI and works fine.

Moreover, if Dolphin is already started and I type "camera:/", I get the
expected result.

All of this happens as an unprivileged user, I didn't test as root. I'm
confused on what is wrong.

Thanks for your feedback!

I'm already working on a more robust "startup" code for Dolphin. This is
just another problem with the current implementation. (Happens with
other kio-slaves too).

This is a different bug, which is fixed in 4.11.4 (bug 327224).
