Reproducible: Didn't try

Steps to Reproduce:
1. Open Digikam
2. Switch to Tags perspective (left hand side)
3. Choose "No Tags" to only display picture with-out tags
4. Choose a picture from the list of pictures
5. Open Tag Manager
6. Enter a new tag in the top left entry field in Tag Manager.
7. Press "+"
8. Crash Report

Actual Results:  
Crash Report

Expected Results:  
New Tag is added to list of tags.

(The same installation hangs - reproducibly, ie. greyed out window, no response, you have to kill it -, when going to the Tags perspective, choosing "No Tags", then pressing a key in the "Enter tag here." entry box in the "Tags" tab on the right hand side.)

Comment 1 Jens Scheidtmann 2016-03-15 15:30:43 UTC

Cannot Reproduce. 
On second try, I was able to create the Tag (on same picture, which gave crash report).

Still I cannot add a Tag to a picture, because the application hangs as descriped in the last sentence.

Comment 2 Jens Scheidtmann 2016-03-15 15:54:24 UTC

I have followed instructions from https://www.digikam.org/contrib for "hangs", but unfortunately, no logs are generated after triggering the hang (ie. there's nothing displayed in DebugView).

Comment 3 Maik Qualmann 2016-03-15 17:34:39 UTC

The cause of the crash will be Bug 343548. If no Tag in the Tag Manager is selected and it is pressed "+", then digiKam crashes. Bug was fixed in digiKam-4.13.

And 5.0.0 will be typically packaged by a contributor for Windows. Be patient....
