[RCU] problem with login after upgrade to 0.3 (password crypted?)

I've just upgraded from 0.2 to 0.3 I'can no more log in ...

Activating

$rcmail_config['imap_debug'] = true;

I can see in the log file <log_dir>/imap that rc sends to the IMAP server the password not as is but " crypted(?) and the server refuses it

[23-Oct-2009 23:02:30 +0200]: S: a001 NO Login failed.

"î`ovG" is not my password!

If I telent the server with the plain real password it logs in!?

/etc/roundcube# telnet localhost 143
