Hi Ellie,

  I made other tests... It's specific to the user/a account.

When user/a SELECT a shared folder where it has access, the imap process 
crashes.

I updated to cyrus-imapd-2.4.20 and the issue still happens.

I also tried to rebuild mailboxes.db with ctl_mboxlist -d -u, I tried to 
rebuild mailboxes.db with an old backup... I tried to delete the 
statuscache and to delete the skipstamp db... the problem still happens.

Thank you
Marco
