Description Alois Wohlschlager 2017-12-10 14:01:52 UTC

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".
