gnus-parameters and (visible . t) problem

[Jochen Küpper]

I am having a problem with gnus-parameters and permanently visible
groups: If I put the following into gnus-parameters, it doesn't do
anything. 
,----
|                         (".*:Science/Konferenzen$"
|                          (visible . t))
`----
Other group-parameter settings work nicely.
If, however, I put it into the Group parameters directly (G P in *Group*)
,----
| ((uidvalidity . "1047986824")
|  (visible . t))
`----
it works like a charm.

GNU Emacs 22.0.50.15 (i686-pc-linux-gnu, GTK+ Version 2.4.14) of 2005-06-07
No Gnus v0.4

Does anybody else see this?

Greetings,
Jochen
