For most task, Kontact works fine for me. However, if I create in the Contacts section an email distribution list, it will work fine as long as Kontact is running but when I close it, the program will crash with signal 11 and once restarted, no trace will be left of my formerly created distribution list.
I get the following traces during the crash :

Application : Kontact (kontact), signal SIGSEGV
0xb5a8743c in nanosleep () from /lib/libc.so.6

All my adress book has been switched to Akonadi, and the data is stored in an Akonadi dir in my home dir.
Contacts appear correctly in the Contacts section and new can be added, so accessing the database doesn't seem to be an issue.
