Thank you for looking at the archives to try and find the answer.  I
presume the things you found were from January this year?  As far as I
can see that thread was never properly resolved :-(

Have you had a look at one of the file locations?  Does the cache file
actually exist, and is it indeed empty?

The cache files are disposable so it might be worth clearing them out.
You should shutdown evolution and make sure nothing evolution related is
running. Then do 

rm -Rf /home/andrea/.cache/evolution/mail/1274249661 2157 26 andrea-desktop

or even just move the mail cache location to one side

mv  /home/andrea/.cache/evolution/mail /home/andrea/.cache/evolution/mail.x

The next time you use Evolution it will take longer to start up (a lot
longer if you have lots of mail) while it downloads the folder and
message lists.

Let us know if it makes a difference.
