[Evolution] Problem getting emails

[Nathan Broderick <nbroderick contractor verio net>]

I recently upgraded from Fedora Core 4 to 5.  Everything runs well on my
machine except I am now having some really strange issues with my email
running through Evolution.  When I first load up Evolution it will load
just fine and the emails will show up.  I can read them and everything
works for about 3 to 5 minutes.  After 3 to 5 minutes, I will see
something like ( Inbox(1) ), but the message will not show up in the
Inbox.  The only way to see any new messages is by stopping Evolution
and starting it again.  Is there a workaround or a bug already posted
for this issue?
