When creating a new album in digikam, the whole application crashes with a segmentation fault upon closing the "New album" dialog. However, the album actually gets created.

Please tell me if I can provide any further information. I love digikam and hope this can be fixed soon as it makes digikam very annoying to use.

Reproducible: Always

Steps to Reproduce:
1. Start digikam.
2. On the main screen, right-click one of the albums.
3. Choose "New..."
4. In the new album dialog, enter any title and click OK

Actual Results:  
digikam crashes with a segmentation fault. However, the album/folder gets actually created and it shown on next start.

Expected Results:  
The album/folder gets created and the new album dialog closes without a crash.
