I'll try and summarise in English, with perhaps a few pointers to 
where I see problems.

Stéphane is trying to get Digikam to run under MacOS X. Installation
seems to have worked, but Digikam crashes. He added a log (with repetitions 
replaced by '...')

When looking through that log, I noticed several things:
(the thing about connection 'Connectiontest' and all queries failing can be 
ignored)

1- there's a warning about needing at least 10 Gb free disk-space:
> ensureFileAllocated: This system misses...
So that must be checked...

2- Phonon can't find or load a suitable backend

3- then there's a lot of those:
> QKqueueFileSystemWatcherEngine::addPaths: open: Too many open files
> QFileSystemWatcher: failed to add paths:
That looks like QKqueueFileSystemWatcherEngine is /opening/ a lot of files 
(as in: one for every image?) and so there's no room later on to open a 
required file (in this case a thread pipe, which is a special kind of 
file). And then Digikam crashes...
(I take the message about Digikam being unable to open a font as a result 
of the 'too many open files')

What I find particularly suspect here is the *QFileSystemWatcher/ 
QKqueueFileSystemWatcherEngine* needing so many open files. All later 
errors are due to lack of file descriptors.

Also, the missing phonon backend might be innocent, or it could indicate a 
missing dependency (or an incomplete or messed-up installation), as does 
the remark in the log concerning ktimezoned.

[Résumé: Digikam plante à cause de trop de fichiers ouverts. 
Au debut du log il y a un remarque comme quoi la partition du disque 
concerné doit avoir au moins *10 Gb* de libre (fonction non implementée 
sous MacOS). Aussi, il y a quelques indications qu'il y a peut-être des 
dependences manquantes]

Bon courage,
