glibc error can not select locales

[Marco van der Grient]

Hello all,
I am using the rc1 iso of 1.7.0

When I do a lin -cr glibc, there is a error:

Error: Expected at least 7 tokens for --checklist, have 4.
Use --help to list options.
xargs: dialog: exited with status 255; aborting

Is this a known problem? And better: is there a hack or solution for it? 
Currently not able to select locales for the installation.

regards,
Marco
