Version:           1.4.0 (using KDE 4.4.4) 
OS:                Linux

I have just updated digikam to the latest SVN and have GSOC libkface, libkmap, kipi and libkexiv2 compiled and installed along with latest versions on kipi-plugins and kdegraphics (with GSOC branches). All compiled well and installed. I have also forcefully removed the same packages from the package manager so I don't double up. Possible duplicate of Bug 244142. But removing the installed libraries didn't help.

Reproducible: Didn't try

Steps to Reproduce:
Start digikam from command line using 'digikam command'

Actual Results:  
Application: digiKam (digikam), signal: Segmentation fault
