Thread:Extension talk:UserAdmin/Purge user throws an error

Hi. I'm running version v0.9.0-0-gdf8645d with MW 1.16.5. When I try to purge a user I get the following error: Fatal error: Wrong parameters for Exception([string $exception [, long $code ]]) in /home/webapps/wpcc/extensions/UserAdmin/SpecialUADMBase.class.php on line 32

Any ideas?

Thanks
