Description Robin Atwood 2014-04-21 12:55:31 UTC

After I upgraded KDE to version 4.13.0 Kontact now segfaults on starting. KDEPIM is masked to stay at 4.4.11. Here is the backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

The various component apps (KMail, KAddressbook, etc) still work correctly. I then recompiled kontact-4.4.11.1-r1 and now the Kontact Introduction page appears but I get a similar segfault as soon as I select a plugin to show:

Same module segfaulting but called from a different place.

Reproducible: Always

Steps to Reproduce:
1. Install KDE 4.13.0
2. Install KDEPIM 4.4.11.1
3. Start Kontact

kontact (4.12.5) on KDE Platform 4.13.1 using Qt 4.8.5

- What I was doing when the application crashed:

Update to KDE 4.13.1 from 4.12, start kontact, get crash practically instantly (as in, I can't tell any time lapse).  Starting kmail independently works fine.

Comment 2 Laurent Montel 2014-05-15 05:28:05 UTC

"kontact (4.12.5) on KDE Platform 4.13.1 using Qt 4.8.5"
why don't use kontact 4.13.1 on kde 4.13.1 ?

Comment 3 Robin Atwood 2014-05-15 06:26:03 UTC

Because after KDE 4.4 KDEPIM became unusable and everything I have read indicates nothing has changed.

Comment 4 Laurent Montel 2014-05-15 06:35:27 UTC

Ok so it's not supported and we never fixed it.
so I close as wontfix
