Thanks for your investigation there. Andrew.

So it's a problem related to Sqlite database initialization.

Marcel, some tips there ?

Andrew, what's about Mysql ? It's the same problem ? (if you can try of course)

Database initialization is only done with the first request, for example when
special(const QByteArray&) is called to list albums. In this method, the slave
takes its time, but that is the sole purpose of an ioslave.

Database initialization is not done in kde_main which is called to construct
the slave. One possible peculiarity here is the creation of a QCoreApplication,
which is needed to load SQL plugins and support DBus.

I am no longer using Windows as I have switched to Ubuntu as my main OS so I
can no longer assist with debugging this issue.

digiKam 2.0 runing on macbook

Marcel,

The problem is the same here on my macbook with 2.0. kioslave do not run and
nothing can be used (no album, no tag, no item, etc...)

IMPORTANT : 1.9.0 run fine here. Same computer, same shared libraries... No
problem...

Conclusion : something is wrong with Database init into 2.x

Any debug output? The equivalent of the ~/.xsession-errors file on linux.

Yes, I can start digiKam from a console and get a backtrace with full debug
info.

Mac is like linux. It's Unix system, but without X11. I will try to get
kioslave debug messages...

Marcel,

Look like i use KDE 4.5.x, not last 4.6.1 available on macport.

Jan said than 2.x run fine with KDE 4.6.1, not KDE 4.5.x.

Anyway, it sound strange no ?

Complete information what worked fine and what not with Mac OS X 10.6.6:

KDE 4.5.x with Digikam 1.9 or 1.8 (not sure anymore which version I had
installed) no problems AFAIR.
KDE 4.6.0 with Digikam 1.9 no thumbnails shown
KDE 4.6.1 with Digiakm 1.9 as well as Digikam 2.0 the thumbnails are shown.

There is also a ticket in the MacPort bug tracker concerning this problem:
https://trac.macports.org/ticket/28308
There are some more logs and some more people state that kdelibs 4.6.1 with
Digikam 1.9.0 is working fine.

Looks like kdelibs are looking for essential services, which are not running,
and then gives up to start the ioslave

Marcel,

I see too, but why with 1.9.0 all work fine, and not 2.0.0.

I installed other KDE application as kate and dolphin which work fine.

I will take the 1.9.0 trace from the console to compare.

The 1.9 trace does not show the error message. Do 1.9 and 2.0 run with the same
kdelibs? Then it cannot really be a kdelibs problem.

The very first error message seems to be this:

digikam(49098)/kio (Slave) KIO::Slave::createSlave: createSlave "digikamtags"
for
KUrl("digikamtags:?databaseType=QSQLITE&databaseName=%2FUsers%2Fagnes%2FDocuments%2FPhotos%2Fdigikam4.db&connectOptions=&hostName=&userName=&password=")
digikam(49098)/kio (KIOConnection) KIO::ConnectionServer::listenForRemote:
Listening on
"local:/private/var/folders/dK/dKQe4t9NHcG6PDrHXkdLhU+++TI/-Tmp-/ksocket-agnes/digikamn49098.slave-socket"
digikam(49098): couldn't create slave: "Cannot talk to klauncher: Did not
receive a reply. Possible causes include: the remote application did not send a
reply, the message bus security policy blocked the reply, the reply timeout
expired, or the network connection was broken."
digikam(49098)/kio (KIOJob) KIO::TransferJob::slotFinished:
KUrl("digikamtags:?databaseType=QSQLITE&databaseName=%2FUsers%2Fagnes%2FDocuments%2FPhotos%2Fdigikam4.db&connectOptions=&hostName=&userName=&password=")

which does not help either.

Maybe some library linking problems? Is there something like
ldd /usr/lib64/kde4/kio_digikamalbums.so
on Mac? Perhaps there are old digikam libraries in a place found when klauncher
loads the ioslave?

Yes, same KDELibs in both. Look my screenshots for details, including
components info dialog.

==> /opt/local/lib/libdigikamcore.1.dylib is the problem ?

digiKam 2.0 running on macbook with KDE 4.6.1

Marcel,

On my macbook, i uninstalled all macport with KDE 4.5.5, and installed again
all. This time KDE 4.6.1 is here.

I only installed 2.0, and all work fine.

I concluded that mixing 1.x and 2.0 is not compatible somwhere in kioslave.

2.0 ioslaves support some new features (faces). I would have thought they are
cross-compatible within limitations... even under Linux, there are often
problems to have to generations of digikam installed in parallel

Marcel,

When i try to use 1.9.0 and 2.0.0 on the same mac computer, i switched between
version to install one over other and vis versa.

Typically, i installed 1.9.0 over 2.0.0 on the system to use 1.9.0, and vis
versa. Both version are installed at the same place.

Shared libs still the same. Only kioslave and digikam core libraries change.
