User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; it; rv:1.9.0.19) Gecko/2010081818 Camino/2.0.4 (MultiLang) (like Firefox/3.0.19)

I use Thunderbird for 7 email accounts, I own the servers and today after I turn off two servers for maintenance so for the two accounts I receive "Nessun Messaggio Scaricato" (No downloaded messages)... this will happen if I try to download selectively from which server I want to download new mails.

Now, if I select "Download all the new messages" happen that I don't get the mail error message, I get at the end of the operations (as you can see in the included link) this message: "Scaricati 4294967294 messaggi" that is "Downloaded 4294967294 messages".

Reproducible: Sometimes

Steps to Reproduce:
1. You need to have more than one email account but you need to have at least two account not working (IE: pop.domain.tld is not reachable);
2. Try to download all the messages from all the accounts;
3. You'll get like 3 on 5 times the wrong email count message.
Actual Results:  
1° time: "Scaricati 4294967294 messaggi"
2° time: "Non ci sono nuovi messaggi nel server" (no new messages in the server)
3° Time: "Scaricati 9123847635 messaggi"
4° time: "Scaricati 4294967294 messaggi" (same as first)
5° time: "Non ci sono nuovi messaggi nel server" (no new messages in the server)

Expected Results:  
"Non ci sono nuovi messaggi nel server" (no new messages in the server)
