SUMMARY
There is a problem in one of my folders.

Refetching complete mailbox.

So, it spends a long time fetching 5Gb of email. But before it can finish,

It does not work any longer. I have to reboot my system. It then repeats the
same cycle. My Fedora-devel folder is a local folder that my imap account gets
filtered into. No amount of refetching imap will fix the local folder. If there
was corruption in the imap cache, sure. But the local folder should just have
the missing entry deleted and life goes on.

How do I fix this? And can akonadi just delete missing entries to fix itself?
I'd rather lose an email than lose all of them.
