I confirm this with FC-6 and Olympus 3030 hardware today, also gphoto2 result.
My FC-6 is a fresh install with all updates per two days ago.
  See comment #33 / all revs are later than those listed.
  Add digiKam is R0.9.0(Using KDE 3.5.5-...fc6), gphoto2 is R2.3.1
Analysis:
With digiKam -- The camera connect request
  First opens a camera window - then opens a fatal error window.
    "Failed to connect to the camera. ..."
With gphoto2 --list ports
  Two ports found prior to camera - ptpip:, and usb:
  Two more found after camera "ON" - usb:001,004, usb:002,003
With gphoto --auto-detect
  Olympus C-2100UZ found (wrong!?  Olympus-3030Z also exists in .fdi)
     May not matter? from inspection of .fdi, 2100UZ and 3030Z seem similar...
     Forcing use of C-3030Z yields same result.
  Two ports listed - usb:, usb:001,005
     I suspect first (without x,y) entry may be incorrect...?
     NOTE! from /proc/bus/usb directory listing
        usb:001,005 does exist with OK UID & permissions
        usb:002,003 does exist with only root perms
        usb:001,004 does not exist (see --list ports above)
With gphoto2 -a
  On the surface the output seems normal and correct
With gphoto2 ... -l
  Fatal error: "Could not release interface 0 (Invalid argument)."
  I have debug trace available --  if useful eamil me for attachment...
  Error began with this:
    "...gphoto2-port(0): Could not query kernel driver of device"
NOTE:
My FC-5 had lesser problem - only root could use USB camera interface.  Today the issue is a more total failure, probably with HAL and setting USB drivers.  I find nothing to adjust nor a workaround.  Advise if I can can further test.

After fiddling around with gphoto2 I finally got my Canon EOS 350D working (again):
1) I had to add users to group plugdev (group camera is not used any more). Well so far simply some permissions.
2) I had to use CANON EOS 350D without(!) PTP mode despite the camera itself is still set to PTP connection (PC connection does not work!). Funny, isn't it?

So at least my bugreport should better be posted to the gphoto dev.
Just for information:

digikam 2:0.8.2-4
libgphoto2-2 2.2.1-12
libgphoto2-2-dev 2.2.1-12
gphoto2 2.2.0-3
on debian testing

Ubuntu are claiming they have been able to fix this issue due to the way Kubuntu KDE finds the gphoto libs..

I can confirm this issue is not fixed in Debian with KDE 3.5.7 and digikam 0.9.2 final. Thus Debian is continuing to ship with a dependency on libgphoto2-2-dev.

I have asked the Ubuntu guys, what changes they made to kdelibs...

This is what pusling has done with Debian kdelibs:

kdelibs (4:3.5.8.dfsg.1-4) unstable; urgency=low

  * Add a patch to allow to dlopen .so files and not only .la files.
    Now kamera, digikam and others doesn't need to depend on -dev packages.

Mark,

Thanks a lots for this patch. This is what i suspected but never find it...

So, the problem come from KDELibs. This one need to be patched in svn to close this file definitively...

Angelo,

For Mandriva package, i recommend you to patch kdelibs temporally, as Debian team...

To KDE-Libs team :

I re-affect this file to your part. The solution to solve it is described by Debian team in #41 and #43. Patch is really simple and easy to test.

Please take a look. Thanks in advance...
