New description:

 We are currently using Pidgin 2.4.1 on Fedora 8 and are seeing problems
 when pasting various items from terminal windows. Usually this happens
 most frequently on pasting IP addresses and such, XMPP logs the user out.

 After some investigation it seems like we found that a unicode character
 that is breaking it:
 U+FEFF


 This is an example of the logout we found in one of the log files:
 <U+FEFF><span style='font-size: small;'>192.168.140.51</span><br/>


 We replicated the issue by pasting this unicode character from a
 charactermap.

Comment:

 Which server are you seeing this with?

 What does the debug log say when this happens?
