[KPhotoAlbum] Re: New snapshot (was : date + setup + help missing =?iso-8859-1?q?+=09database?=)

[Jesper K. Pedersen]

I dont do any loading/unloading of libraries in KPA (except indirectly for 
plugins). So this would have to be a Qt or KDE problem.

On the other hand, I can't believe either to have such a bug, as it would hit 
us all over the place, so I tend to beleive that it is simply an oddity of 
using valgrind.

Cheers
Jesper.
