Installed from:    Mandriva RPMs

When launching digikam, it scan my pictures folder and crash when reading picture with an empty Exif.GPSInfo.GPSAltitude value. If I open the file with showfoto, showfoto crash only when I open de marble(geolocation) tab.

If i try to get exif data with exiv2(0.17.1) I get:
- this picture is loaded fine:
