sorry for the arcane format... drkonqi on ubuntu 14.04 can't seem to file this bug directly so I need to copy and paste. I hope it's useful.


Application: digikam (4.2.0)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-35-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was adding keywords to photos, and entering a new keyword that could have been an extended version of another.
I had one keyword already marked and wanted to create a new keyword on top level.

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

Possible duplicates by query: bug 338448, bug 338358, bug 337607, bug 337278, bug 337258.

Reproducible: Always

Steps to Reproduce:
1. select an image
2. select an existing tag
3. type text for a new tag and press enter
4. there should now be a popup/context menu suggesting to either create a new tag, or to create a new tag underneath the current tag
5. select "create a new tag"

Actual Results:  
digikam crashes

Expected Results:  
digikam adds the tag and enables its checkbox
