Xbian update failing

[Baz8755]

I am currently running a clean install of Beta 1.1 and was informed in the linux update app that a new version of xBian is available, when I try and perform the update I get the following errors

/usr/local/include/xbian-config/modules/updates/functions: line 141: xbian-update;1.0-1.1;1.0-1.2: syntax error: invalid arithmetic operator (error token is ";1.0-1.1;1.0-1.2")
/usr/local/include/xbian-config/modules/updates/functions: line 142: xbian-update;1.0-1.1;1.0-1.2: syntax error: invalid arithmetic operator (error token is ";1.0-1.1;1.0-1.2")
(standard_in) 1: syntax error
(standard_in) 1: syntax error


Any ideas?

Cheers
