[Evolution] Error trying to expunge messages

[Simone Peruzzi <simone peruzzi ego-gw it>]

 Hi to all the member of this mailing list.

I'm here to disturb you just to know, why since few days to now i can't
Expunge anymore my Evolution mailbox.
I use Evolution 1.2.0, and when i try to expunge the deleted messages i
received this error:
"Error while 'Expunging folder':
 Error storing 'Local folders/inbox': Summary and folder mismatch, even
after a sync'"

Do you know how to fix this particular problem? By the way the
application is working fine...i can receive or send message...just the
problem on erase the messages.
Many thanks by now...
Simone.
