--- Comment #6 from Martin Steigerwald ---
Here another one during runtime of Akonadi. I found another way to reliably
reproduce this:
- download new mails via POP3 resource
- filter them
Also killing the akonadi maildir resource process will make KMail respond
immediately. I can do this some times, until KMail complains it is not working
probably and marks all folders in red. Then I have to restart the resource
manually. I bet thats a endless restart prevention thing.
(gdb) continue
Continuing.
