Some groups cannot be entered

I performed a sweep over the Gmane groups but I was unable to visit some
of them. I _think_ these groups are supposed to exist and be non-empty
(the groups are only created when a message arrives, right?) but as of
last Friday, these could not be entered.

The Python client I wrote simply fails with "423 No articles in 1-".
The LIST ACTIVE command indicated a number of articles should be present
but the GROUP command indicated the last number to be 0. When I try to
visit them in Gnus, I get "Couldn't enter". Is there some sort of index
error here?
