Sentry Crash Report:

Description kde 2014-12-06 14:47:07 UTC 
This doesn't only happens when I do something ktp, but anything ktp related. Especially on login I get around 30 or more crashes from kded5 resulting in plasma5 not to startup entirely.

sadly there is something wrong withing the static initialization of the shared library file, so the backtrace doesn't show much information:

Application: kded5 (kded5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

After removing "/usr/lib64/qt5/plugins/kded_accounts.so" everything seems to work again.

Reproducible: Always

Steps to Reproduce:
1. install
2. do kded involving activities (right-click, open systemsettings, ...)

Actual Results:  
crash

Expected Results:  
no crash
Comment 1 demm 2014-12-07 00:20:25 UTC 
Confirmed here with Qt 5.4rc, all the latest git checkouts of the whole ktp group, all build on frameworks 5.5.0.
Plasma 5 starts fine, contact-list works, if compiled without kaccounts-integration (ofc, not much use that way), same behavior as described above, when kaccounts-integration is added.
Comment 2 kde 2014-12-07 09:34:20 UTC 
one positive thing is, that as long as all your accounts are already added, you don't need kaccounts-integrations for telepathy anymore, but having all these crashes and hangs only because of installing is really bad.
Comment 3 kde 2014-12-07 09:35:54 UTC 
on a side note: I use KF 5.4.0
Comment 4 Martin Klapetek 2014-12-08 10:11:13 UTC 
It crashes because of some akonadi stuff, see the first 4 lines of the Thread 1 backtrace. I'm going to make the akonadi plugin optional for now, but ultimately this crash comes from your akonadi setup, sorry.
Comment 5 Martin Klapetek 2014-12-08 10:12:18 UTC 
Also, try to install akonadi debug packages and see what the backtrace will show then, it will be easier for akonadi folks to fix it.

Git commit 72fcb217e0da8eddb0c0fbcb66c805e8bbbb3e9c by Martin Klapetek.
Committed on 08/12/2014 at 17:20.
Pushed by mklapetek into branch 'master'.

Build the Akonadi plugin as a standalone plugin and make it optional
