cannot open mails with attachment

[vikrant]

After upgrade to latest svn snapshot and updating the main.inc.php and db.inc.php cannot open any mails with attachment.

Other mails open fine.

Confirmed on two different installations I have using SVN rev 266.

I get the following in roundcube's error log:

[27-Jun-2006 10:00:28] PHP Fatal error:  Using $this when not in object context in /usr/home/webmail/roundcubemail/program/include/rcube_imap.inc on line 1722

program/include/rcube_imap.inc line 1722 is:

return rcube_charset_convert($input, $this->default_charset);

It appears to have been introduced when the default charset changes were made in rev 264 (See http://trac.roundcube.net/trac.cgi/changeset/264 )
