[Galene] Server error: illegal group name

["Rémi Nollet" <nollet@irif.fr>]

Hi everyone,

I have a problem with my Galene server and was hoping someone could help me.

When I try to connect a group, such as
https://galene.letrec.fun/group/public/
I get two red alert messages :
     Disconnected
and
     The server said: illegal group name.

I see nothing in the console.

This group description in groups/public.json is:

{
   "public": true,
   "op": [{"username":"remi"}],
   "presenter": [{}],
   "max-clients": 100
}

Note that when I try to connect a non-existing group, such as
https://galene.letrec.fun/group/trululu
I get the expected Page not found error.

I am using the last master (7d01f0339b0c195ab5d4b374595a0b2d1838c7ae).

Note also that I recently updated the binary after a long period of 
inactivity, so I may be missing a change in the configuration. But after 
carefully reading the doc on galene.org, I could not see what I am doing 
wrong.

Do you have any idea where my problem might come from?

Thanks in advance,
