Hi Volker, Hi Maximiliano ! This error is still in stretch. But I've got it in an i386-environment. I don't want to make a new Bug-Report, but document, that it still exists. I described it here: https://bugs.kde.org/show_bug.cgi?id=382635
As I described there, the error occurs always I start kaddressbook. I (can't) use kaddressbook 4:16.04.3-3. My Kernel is linux-image-4.9.0-3-686-pae (4.9.30-2+deb9u). With a new user it starts - as in Jessie. Here are my error- messages, when I start it from Konsole (bash): QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x80663e78) "kaddressbook_9177_mTcCx7" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x80663e78) "kaddressbook_9177_e22nIP" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x80663e78) "kaddressbook_9177_tOmGTd" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x80663e78) "kaddressbook_9177_9QZzTP" false Database "akonadi" opened using driver "QMYSQL" Database "akonadi" opened using driver "QMYSQL" New notification bus: "/subscriber/kaddressbook_9177_mTcCx7" Database "akonadi" opened using driver "QMYSQL" New notification bus: "/subscriber/kaddressbook_9177_e22nIP" org.kde.akonadi.ETM: GEN true false true org.kde.akonadi.ETM: collection: QVector() Database "akonadi" opened using driver "QMYSQL" New notification bus: "/subscriber/kaddressbook_9177_tOmGTd" Database "akonadi" opened using driver "QMYSQL" Database "akonadi" opened using driver "QMYSQL" New notification bus: "/subscriber/kaddressbook_9177_9QZzTP" KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = kaddressbook path = /usr/bin pid = 9177 KCrash: Arguments: /usr/bin/kaddressbook KCrash: Attempting to start /usr/lib/i386-linux-gnu/libexec/drkonqi from kdeinit sock_file=/run/user/1000/kdeinit5__0 Shutting down "kaddressbook-1186278907" ...
