Comment 2 Benjamin M 2011-08-12 13:33:56 UTC
I can confirm that on KDE 4.7, Qt 4.7.3, openSUSE 11.4. I was removing empty categories that had at some point popped up. This happens every time with the 2nd - 5th empty tag that I remove. 

I compared backtraces, and they look pretty alike. Idk if mine will still be needed?

New crash information added by DrKonqi

kontact (4.7.4) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4

- What I was doing when the application crashed:
I was attempting to delete empty tags from the Contact editor.

- Unusual behavior I noticed:
Empty tags keeps being created both in KMail and the Contact part (KABC?). ToDos (and Calendar?) seems to behave alright.

- Custom settings of the application:
I use Cal-/CardDAV resources with ownCloud as backend. Before that I used Memotoo.com with traditional resources and had the same problem.

Comment 4 Christophe Marin 2012-05-17 21:45:34 UTC
Is that still reproducible with recent kaddressbook versions ?
Comment 5 Thomas Tanghus 2012-05-17 21:59:46 UTC
It seems to work like a charm with Kontact 4.8.2. Very nice to be able to use the tags :-)
Comment 6 Christophe Marin 2012-05-18 08:07:14 UTC
Thanks. Closing

Backtrace on 4.8.3

I still have a bit of a problem. The empty phantom tags are gone, and I can delete a tag that I had just created. But I cannot delete a tag that is actually in use. I tried deleting the "Watched" tag, and only got an error sound. At the second attempt, a crash gave me the attached backtrace.

I'm happy some work has gone into it (thank you!). Hope this will be resolved soon (or that maybe my problem is a different one).

I just tried the same under KDE 4.8.3, KDEPIM 4.8.2 and Qt 4.8.1 with no problems and I could see in my ownCloud that it actually removed the category ;-)

Looking at your bt it looks like a Qt crash, so maybe this issue should be filed upstream?
