Corrupted .dat file

Using master.

I suppose the issue appeared because of a short power outage.

The symptoms:
- The mailfilter agent was using 50% cpu after restart,
- The memory usage keeps increasing
- The mailfilter agent appears offline in akonadiconsole (despite having Online=true in agent_config_akonadi_mailfilter_agent)
- The resource doesn't react to dbus calls.

Renaming agent_config_akonadi_mailfilter_agent_changes.dat fixed the issue. 
and the issue is back as soon as the corrupted file is restored.

>From bug 298121:

Efter logging into KDE4 my system becomes sluggish for at least 10 - 15 minutes. The problem seems to be that akonadi_agent_launcher claims 1.7GB of my 2GB memory. 
During the first minute after login akonadi_agent_launcher rapidly claims more and more  RAM until 85-90% of my RAM is consumed. During these 10-15 minutes my hard disk is frantically active and my system is in practice not usable. 

The parent process to akonadi_agent_launcher is akonadi_control.

Deleting the concerned .dat file fixed the issue for the reporter

-- Information about the crash:
- What I was doing when the application crashed:

My system was completely frozen due to a kernel panic, so I manually
powered it down and started again.  After boot, I got this crash,
restarted the mailfilter_agent, and then got it again.

I saw something similar after upgrading from KDE 4.7 to 4.8.  I suspect
some kind of data corruption or unexpected condition causes
mailfter_agent to crash.  When this happened before, it took deleting
all the local data and then re-importing it to get mailfilter_agent to
work again.

Deleting the concerned .dat file also fixed the issue for the reporter.

akonadi_mailfilter_agent is shipped as part of kmail, so I think the
product is wrong on this bug.

no, the trick above worked also for other Akonadi resources
