NB: I can download using `gphoto2 -P` so able to work, but would like to use Digikam interface...

It's a packaging issue. The official Digikam 2.1.1 packages from Ubuntu is built intentionally without libgphoto2 support to prevent crashes in libdc1394. Think this was the only way at the moment to be able to get Digikam 2.x into Ubuntu 11.10 before freeze.

I have built my packages on my PPA against OpenCV 2.3.1 and will have patched libdc1394 to solve this issue instead of disable the features that comes with libgphoto2 support.

Thanks Philips for the feedback. i mark this file as UPSTREAM

I have the same problem with kubuntu 11.10 and digikam 2.1 
64bit operating system.

My camera is fujifilm finepix s4000

Kubuntu 11.10 32bit.
 Digikam 2.1.1 KDE 4.7.2
Same problem with Kodak Easyshare M341 -detects but will not import

That crashes. :(

brian@defiant:~$ digikam 
QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work.
digikam: symbol lookup error: digikam: undefined symbol: _ZN11KExiv2Iface14AltLangStrEdit15setLinesVisibleEj

Brian,

it's a binary compatibility issue with libkexiv2 on your system...

Gilles Caulier

Brian, I see that you use my PPA then make sure that you have installed and use my rebuilt versions of libkexiv2-10, libexiv2-11 and libkipi8. They are all newer version than what comes with stock Ubuntu and KDE. My Digikam packages are all built against them and also need them or Digikam will not start with error messages about symbol lookup error. 

/Philip

I installed the packages you mentioned from your PPA, and got digiKam to start successfully.  I tried to import from my camera and the app crashed.

Did you also update libdc1394-22 from my PPA? 

I think crashes like this was the reason they disabled gphoto2 support in Digikam 2.1.1 with Ubuntu 11.10, but as far as I know it should work with a package update from my PPA on Ubuntu 11.10. 

If it's not a new bug somehow but I think this is the infamous libdc1394, libphoto2 and opencv bug.

Kubuntu 11.10
KDE 4.7.2

I completely removed Digikam & Kipi including configuration files via synaptic package manager and then I followed Philip's instructions at 
http://scribblesandsnaps.wordpress.com/2011/03/09/install-the-latest-beta-of-digikam-on-ubuntu-10-10/
Can't remember whether or not it required reboot

Digikam 2.3.0 is now working excellently - thanks Philip

This is off topic for this bug report and are Ubuntu packaging issues but if anyone read this here we go. 

Installing the packages named digikam2 and kipi-plugins2 is depreciated since digikam 2.1.1 with my PPA (that guide is a bit old) and you should now install package names digikam and kipi-plugins. digikam2 and kipi-plugins2 was only transitional names between the digikam 1.x and 2.x shift.

I have left digikam2 and kipi-plugins2 in my own packages for backward compatibility so it works but are no official package names.

Thanks Phillip, upgrading libdc1394-22 to your PPA version resolved the issue, and I am now able to import from my camera! :)

Are these fixes planned to get into Ubuntu repos in the future?

Thanks, after the update programs and libdc from Phillip's PPA, Digikam can  import photos from FinePix s3200.
