Backup feature broken

I'm trying to setup backups over SSH, just trying one server at the moment and i keep getting the following error.

Starting backup of 1 domains to ssh://backupuser:password@remotehost.tld/home/backupuser/backups/domain.tgz .. Creating backup for virtual server somedomain.net ..

Creating TAR file of home directory .. .. done

Creating final backup archive .. .. archive failed! /bin/sh: /tmp/.webmin/568772_2_backup.cgi: Is a directory

Backup failed! See the progress output above for the reason why.

<b>Just realised that all the backup options seem to be broken now, when trying a local backup i get[/b>

Starting backup of 1 domains to /root/backups/ .. Creating backup for virtual server somedomain.net ..

Creating TAR file of home directory .. .. TAR failed! /bin/sh: /root/backups/somedomain.net.tar.gz: No such file or directory

This was working last night, i got an all ok email from the backup system, i've upgraded to 3.02 this morning and its all stopped working
