[Mailman-Developers] hi, i have an unconfortable error with mailman 2.0.8

[Roger Peña Escobio]

yesterday i upgrade mailman 2.0.6 to 2.0.8 and since then i started 
getting this behavior:

when i use the admin web interface, after authenticated, any other page 
that i try to see i get this messages:
"Error decoding authorization cookie"

i use koqueror, the version that came with redhat-7.2, but if i use IE or 
lynx everything goes fine :-(

i try to find what change from 2.0.6 to 2.0.8  make this possible but i 
couldn't find anything understandable by me

anybody with the same problem?

thank for any tip
roger
