[Tracker] tracker not indexing evolution mails correctly

[Thomas Mittelstaedt <tmstaedt t-mittelstaedt de>]

I just removed the .cache/tracker directory, and re-indexed and still
some mails are not found when searching for terms found in the body of
the message. I am running version 0.6.6 on ubuntu hardy and evolution
2.22.3.1

Thanks for hints on how to track this down.
