I have, rarely, managed to get errors like that or similar, usually by doing something that surprised the firmware. e.g. Adding multiple copies of a book with the same ASIN, or modifying a book without first telling the firmware it was deleted (by deleting it and afterwards resending).

The issue will be corruption of the Content Catalog which is a database stored in /var/local/cc.db -- if you delete this (requires jailbreak, plus kterm or USBNetwork for rootfs access) then the Kindle will rebuild the Library list from scratch and resync collections from the Cloud.

Resetting the device works too... because resetting the device clears the contents of /var/local/ in addition to deregistering and wiping the userstore.
But it is not necessary if you are jailbroken.

In fact, if you are jailbroken I highly encourage you to not reset since if you do it will damage the jailbreak and require immediate reinstall of the bridge/hotfix, and if you get a firmware update in the meantime you will have to begin from scratch to jailbreak your device again. (At least it is possible again, now we have a universal factory image jailbreak to replace the 5.6.5-specific one.)
