--- Comment #5 from Eric MSP Veith <eve...@wwweb-library.net> --- It took me a bit of fiddeling and much patience to encouter this bug with GDB. But here it is. I've got a backtrace and a core dump. The core dump file is quite big, so I've uploaded it to an external source (6,7 MB > 4000kB; sorry, self-signed cert...): - https://oc.veith-m.de/index.php/s/fK7kcbw7mYQORPg - https://oc.veith-m.de/index.php/s/pLRB5I0VBPE2rdl I'm not sure whether this is actually a KDE-specific bug? Perhaps only something in KDE triggers it, I don't see any KDE libs in the backtrace. But I'm by no means an expert here; I hope this helps somebody. Here are the last few lines before emitting a SIGSEGV: [...] QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_followupreminder_agent_28779_PP6Fkp" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_ical_resource_3_28781_zVEkXR" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_davgroupware_resource_2_28778_uaMY6p" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_archivemail_agent_28775_ubx5xw" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_mailfilter_agent_28801_MpmVCD" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_maildir_resource_5_28794_K6eQWS" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_maildispatcher_agent_28799_xR5u02" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_imap_resource_6_28790_7aAYVF" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_sendlater_agent_28806_FPSn8U" false Cannot pause an inactive timer Cannot pause an inactive timer QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_imap_resource_5_28786_7wZJ5V" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_newmailnotifier_agent_28804_e4MqgF" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_notes_agent_28805_lXx6g1" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_invitations_agent_0_28792_q6189K" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_indexing_agent_28791_GC7RfJ" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_migration_agent_28803_YOhJyk" false QDBusObjectPath Akonadi::Server::NotificationManager::subscribe(const QString&, bool) Akonadi::Server::NotificationManager(0x85b830) "akonadi_ical_resource_4_28783_srS5ST" false *** Error in `/usr/bin/akonadi_control': malloc(): memory corruption (fast): 0x00007fffd8018e3c *** [New Thread 0x7fffde0b0700 (LWP 28765)] [New Thread 0x7fffecb6d700 (LWP 28764)] Program received signal SIGSEGV, Segmentation fault. 0x00007ffff5aebb2e in _dbus_counter_notify (counter=0x7fffd800dae0) at dbus-resources.c:187 187 dbus-resources.c: Datei oder Verzeichnis nicht gefunden.
