Reconstruct removes @domain from mboxlist

[Ramprasad]

Hi,

   I have a cyrus-imapd 2.3.7  on RHEL 5 with multiple domains

When I reconstruct a user mailbox on the primary domain it works fine  
, but when any secondary domain mailbox is reconstructed the user is  
unable to login

when I dump the mailbox list I find that the users permissions are removed

domain.tld!user.ram 0 1 ram at domain.tld lrswipda

becomes ( after reconstruct )

domain.tld!user.ram 0 1 ram lrswipda

Why is reconstruct corrupting the mailboxes.db
