Can you reproduce this by talking imap protocol directly? telnet localhost 143 a login user pass b delete mailboxname or possibly b rename mailboxname Trash/mailboxname gdb backtrace would be helpful: http://dovecot.org/bugreport.html I couldn't reproduce this, so it's also possible that it's already been fixed since beta6.
