Bug 227706

Version:           4.4 (using 4.4.00 (KDE 4.4.0), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.31-19-generic

After having kontact open for some time (a day or more) I go to edit my todo list.  It appears everything is working fine.  Then if I close kontact and reboot, or restart akonadi all my edits are lost.  This issue is sort of a silent killer since I rarely reboot or restart kontact and so weeks could go by and my todo list is messed up quite a bit when I do.  My resource file isn't edited either.  This only happens after a while of running.  Most of the time things work just fine.

Here is the output from akonadiserver when I try to edit the todo list...
