Digikam crashed after I changed from one to another adjacent folders a few times.  When I restarted digikam it came up with the folder it opened up the previous time.  

Reproducible: Always

Steps to Reproduce:
1. Open digikam
2. Switch between a few adjacent folders (same hierarchy level) a few times.


Actual Results:  
The application crashed every time.

Expected Results:  
Just change from album folder to the next without crashing.

Application: digikam (3.5.0)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-43-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

- Looking at pictures in adjacent folders and switching between folders.
- I had updated the system from Kubuntu 12.04 to Kubuntu 14.04 a day ago.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
