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.
