[Mediawiki-l] Error on resetting password

[Raul B ö hm]

Hello,

I have a 

MediaWiki      1.13.1
PHP     5.2.6 (apache2handler)
MySQL     5.0.32-Debian_7etch6-log

I forgot my password and done the send new password thrue mail procedure.
After entering the new password twice, I've got this error message (I
used special character in password):

Fatal error: Unsupported operand types in .../wiki/includes/User.php on line
