[KPhotoAlbum] Crash on exit

[Robert Krawitz]

I've had a crash on exit for a while.  I finally got around to
bisecting it, and it turns out to be when the map stuff was added:

e59af35875adc3e9081b471bd9f17c0fb9ddc30e is the first bad commit
commit e59af35875adc3e9081b471bd9f17c0fb9ddc30e
Author: Tobias Leupold <tobias.leupold at web.de>
Date:   Wed Dec 17 15:37:55 2014 +0100

    * Added a map view widget using libkgeomap to display one or more
      image coordiantes.
          * Added functions to read out the GPS information from an
      image's EXIF headers.

    This is the result of a longer development (with a lot of testing
    back and forth).
        Also developed by Johannes Zarl, see the annotation_map_2
    branch.

In case it matters, I get the following warning during link:

Linking CXX executable kphotoalbum
/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: warning: libmarblewidget.so.19, needed by /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/libkgeomap.so, may conflict with libmarblewidget.so.20

Also, none of my images are geotagged.
