[wp-testers] new site urls missing backslashes

[Matthew Willse]

I'm testing 3.0 beta, installed today from scratch. I have turned on 
multi site using sub-directories.

Actually adding a site does not work. The paths and urls are missing 
their backslashes.

For example: Adding site with address "test1" yields...

domain: www.example.com
path: exampletest1/
siteurl: http://www.example.comexampletest1/
home: http://www.example.comexampletest1/

Any suggestions?
thanks!
