 I am using "master" with ID 6b18ec66cb324ee3462a64856852bc98f612be92
 from kdepimlibs.
 The crash occurs at the file

 /home/guy-kde/kdesvn/kdepimlibs/akonadi/specialcollectionsrequestjob.cpp
 at the lines 200-204 (I had some kDebug(... lines, so the linenumbers 
 at
 the crash below are light different). These lines were written by 
 Sergio Martins
 commit 6768a9646e81472e4640bec3e7d5cda10699251e

 Yes, the crash it little big...

 right, from the file
   /home/guy-kde/kdesvn/kdepimlibs/akonadi/specialcollections.cpp
 which included
   /home/guy-kde/kdesvn/kdepimlibs/akonadi/specialcollections_p.h

 right, which contains:
   [SpecialCollections]
   DefaultResourceId=akonadi_maildir_resource_0

 NOT at me!
 Is it the bug?
