           Summary: Crash when migrating from 9.4 on Ubuntu Intrepid Ibex
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]

Version:           svn (after 10.0 beta8) (using KDE 4.1.0)

At the first run of a digikam 10.x (compiled from SVN) and migrating from a 9.4
it crashed. On the console I could see this error:

Once I restart digikam it restarts, but then I cannot see any image, and I get
the following errors:

digikam(32145) Digikam::AlbumLister::slotResult: Failed to list url:  "Could
not start process Unable to create io-slave:
klauncher said: Unknown protocol 'digikamalbums'.
."

I'm using digikam from gnome, and instead of installing everything in /usr I
installed it in /opt.

At the moment I've no digikam working and I cannot access my albums.

Your problem in comment 2 is typical for Ubuntu and results from not finding
the ioslave libraries (kio_digikamalbums.so etc.), which are somehow not
installed to the right place

I improved things linking everything I found in
/opt/lib/kde4 and /opt/share/kde4/{services,servicetypes} in the corresponding
paths in /usr.

Now I can see the images. But I still have serious problem, but I don't know if
they are bugs or just problems with my installation.

I asked this on the digikam-users mailing list, but is there a way to tell KDE4
to
look for libraries and resources on a different path as well? I installed
digikam in /opt because in /usr I just want to have package managed software.

There used to be $KDEDIR and $KDEDIRS, dont know if this still works in KDE4.
It's usually better to install to directories as found by CMake if you dont
have experience with this packaging stuff.

The code causing this crash was a temporary crash and is now removed. It could
have been a simple race condition. You can retest by removing your digikam4.db
(simply restore it later). Please report any problems, or we can close this.

This problem is relevant of digiKam KIO slaves which have been dropped since
5.0.0 by a multi-threaded interface to query the database. It will never
reproducible.
