Problems with libexiv2 after installing digikam along stable

[Simon A. Eugster]

Morning,

I've got a tiny problem, which is that every kde app is crashing as soon as it tries to read exif information from a file. This is e.g.
* When opening a .jpg file with dolphin
* When displaying a .jpg file with gwenview
* When starting kdevelop (which really hurts -- I've tried to display a .jpg inside kdevelop, and now it crashes on startup already)
* And so on.

I've been folllowing this tutorial: http://www.digikam.org/drupal/download?q=download/SvnAlongStable
So, the SVN libexiv2 is at /usr/local/lib, whileas the debian libexiv2-6 is at /usr/lib. Interestingly (and bad for me) some programs seem to just ignore this fact, namely all above and more:

Or, when starting gwenview and opening a directory containing jpg files:

So they are accessing the /usr/local lib and not the /usr lib. Although installed via ordinary debian package.

Any hint?
(It's not a wrong symbolic link:
$ ls -la /usr/lib/libexiv2.so.6
lrwxrwxrwx 1 root root 17 16. Jun 19:50 /usr/lib/libexiv2.so.6 -> libexiv2.so.6.0.0)
