After deleting the "timeout" value and de-focusing the field, the blank timeout value is saved and the server becomes useless due to cascading "badarg" errors

1.) Log in as an admin.
2.) Go to "Configuration" section of Futon.
3.) Double-click timeout value to get edit field
4.) Press the delete/backspace key to erase the current value in order to enter a new value.
5.) Click outside the field to lose focus.

The editor field disappears and can't be reactivated because the effective width of the "timeout" value is 0. Once CouchDB writes the timeout value, no admin operations can be conducted due to "badarg" errors.

Restarting Couchbase Server didn't help.

I was able to get things going again by setting "require_valid_user" to "false" in local.ini, then going in and changing the timeout.

I expected the configuration to revert to the default timeout if I don't enter one. I don't expect un-focusing a field from a stray mouse click to have a catastrophic effect on the server.
