[Evolution] I can't see the emails : No Sender, no body no subject

Hi there,
IO just encountered this weird situation. Evolution  was working
perfectly when I tried to add my native language to Redhat 8.0, but I
kept using U.S. english keyboard and locale. Now when I open the
Evolution, I can't see no summary text (only some small tiny weather
icons) and all of the emails don't have the normal header : Sender,
sunject, recipent ... And the worse, some of the even don't have the
message body. I am sure there are something inside them, because when I
go to File menu and ask for a print preview, everything is there and I
can see the email !!!!
Anybody have any idea ?
Thanks

Hamid
