mozilla composer asks "would you like to subscribe to <newsgroup name>"

["H.S." <hs.samix@gmail.com>]

Hi,

Since yesterday or so I noticed that in gmane newsgroup account,
whenever I do any operation: change to a another newsgroup, grab new
messages; mozilla composer prompt me with a message box asking:
"would you like to subscribe to <newsgroup name>"

This is happening only for gmane newsgroups. I created a new account too
but that also has the same problem.

Anybody else having this problem?

thanks,
->HS
