New installation of 3.5.0 on Kubuntu 14.04.2 (LTS).
Crash occurs while splash screen displays.  I believe the top line on the splash says "Reading database."
Happens every time.  I have purged the install and reinstalled with no change.

Reproducible: Always

Steps to Reproduce:
1. Click icon to start digikam
2. Note splash screen appears
3. See C rash Assistant appear

Actual Results:  
Splash screen displays a number of legends.  At "Reading database" application crashes

Expected Results:  
Opened the main application window and worked.  Incidentally, Showfoto (also newly installed) does work.

KDE Platform Version: 4.13.3
Qt Version: 4.8.6
