When opening KMail, akonadi_mbox_resource instantly crashes with a segmentation fault. This seems to happen before the mail is read from the local spool. Backtrace: Application: akonadi_mbox_resource (akonadi_mbox_resource), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
