SUMMARY
There is a problem in one of my folders.
Aug  1 09:28:19 x2 akonadi_imap_resource[3094]: org.kde.pim.imapresource: Detected inconsistency in local cache, we're missing some messages. Server:  165935  Local:  9
Aug  1 09:28:19 x2 akonadi_imap_resource[3094]: org.kde.pim.imapresource: Refetching complete mailbox.

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

Aug  1 10:05:04 x2 akonadi_mixedmaildir_resource[3108]: org.kde.pim.mixedmaildirresource: Failed to read item "1442061842.R339.x2" in Maildir "/home/sgrubb/.kde/share/apps/kmail/mail/Fedora-devel"
Aug  1 10:06:11 x2 akonadi_mixedmaildir_resource[3108]: org.kde.pim.mixedmaildirresource: Store fetch for new item "" in collection -124 , "" did not return the expected item. error= 102 , "Error while reading mails from folder Fedora-devel"
Aug  1 10:06:15 x2 akonadi_mixedmaildir_resource[3108]: org.kde.pim.mixedmaildirresource: Failed to read item "1442061842.R339.x2" in Maildir "/home/sgrubb/.kde/share/apps/kmail/mail/Fedora-devel"
Aug  1 10:06:15 x2 akonadi_mixedmaildir_resource[3108]: org.kde.pim.mixedmaildirresource: Store fetch for new item "" in collection -124 , "" did not return the expected item. error= 102 , "Error while reading mails from folder Fedora-devel"
Aug  1 12:09:43 x2 akonadi_indexing_agent[3100]: org.kde.pim.akonadicore: Failed to open external payload: "/home/sgrubb/.local/share/akonadi/file_db_data/30/9573130_r0" "No such file or directory"
Aug  1 12:09:43 x2 akonadi_indexing_agent[3100]: org.kde.pim.akonadicore: Failed to open external payload: "/home/sgrubb/.local/share/akonadi/file_db_data/33/9573133_r0" "No such file or directory"

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.
