The message actually has a frowning face icon and says:

No such nick or channel
irc1.smashthestack.org

Why do you believe that the server should know about the resource you 
are referencing?

Without further information, this looks like user error or a problem 
with the IRC server that you are using.

The technical cause of this message is that the server returned a 401 or 
406 response.

 From http://irchelp.org/irchelp/rfc/chapter6.html#c6_1

401
     ERR_NOSUCHNICK
     "<nickname> :No such nick/channel"
     - Used to indicate the nickname parameter supplied to a command
       is currently unused.

406
     ERR_WASNOSUCHNICK
     "<nickname> :There was no such nickname"
     - Returned by WHOWAS to indicate there is no history information
       for that nickname.

Assuming pidgin is substituting the correct information into the 
message, and the server is providing it correctly, my guess would be 
that you have entered a server address when you should have entered a 
nickname.

The pidgin debug log may tell you which command failed, if it was a 401 
response.

PS Please do not try to force replies off the mailing list (you had a 
Reply-To header set).
