[chef] problem listing clients in 0.9.8

[Boris Shulman < >]

Hi,

I've installed chef 0.9.8 on centos via rpm install. I'm getting an
error when trying to list existing clients via knife:


 HTTP Request Returned 500 Internal Server Error: Option name's value
does not match regular expression /^[\-[:alnum:]_\.]+$/

        from /usr/bin/knife:19:in `load'

From web ui I can't list clients either.

By the way other operations on client work just fine, including
showing info for a specific client. Is it possible that the problem is
that I'm using the same couchdb database from 0.9.6?
