Yes, this gives important information: It hangs while installing the directory 
watch. For each album directory, digikam creates a KDirWatch (so it happens 
while the albums are read from database).

That's the point (#8->#7) where digikams code is left. #7-#5 is kdelibs, #4-#2 
is libfam, which together with a daemon provides one way to monitor 
directories. All this is completely opaque to digikam.

So the problem can be in
- kdelibs
- libfam
- famd
- kernel

Any "unusual" directories in your album hierarchy? Does it also happen with 
other directories?

That's how it is supposed to be.
