Application: akonadi_googlecontacts_resource (4.10)
KDE Platform Version: 4.10.1 (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.8.2 x86_64
Distribution: Debian GNU/Linux 7.0 (wheezy)

-- Information about the crash:
I just inserted a new contact to my addressbook, and after selecting a nepomuk category it crashed. Since then on every start of the resource I get the crash as attached on the backtrace.

I observed that modifying a contact adding the category also causes the crash.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Google Contacts (akonadi_googlecontacts_resource), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
