[Evolution] MailDir + unSYNC + Invalid Root on Evo 1.4.6

[Ow Mun Heng <Ow Mun Heng wdc com>]

This is the case

OS : Gentoo
Evo 1.4.6
Mailing List (~40,000 emails, 295MB)
Office Emails  (2088 emails, 533MB)
/home is XFS
Laptop Hard Drive (hdparm ~30MB/s)

I migrated from Mbox format to MailDir format hoping that I would see
faster performance from this. But the results are that the opposite is
true.

I frequently get this unSYNC flag and it keeps hanging because it
reports the message index is out of sync. And it will force a Re-Sync
and thus, Evo will stop responding while it does it's Job.

I've also had a number of hard-freezes.

This is what it spits out, (running evo from the command line)

-----This was one cause of freeze(from bug-buddy)----

I also see a lot of these error messages each time it tries to re-sync

I'm in the midst of refreshing my Fedora Mail list folders into 3 months period.
