The "Pinging IMAP server <blah>" message you get in Evolution is
actually not a PING (RFC 2925). but a NOOP request to the server, just
to keep the connection alive. 

There was an issue in 2.0.x versions of Evolution where it used to lock
up when sending a NOOP to the server, This has been fixed in the later
releases. Upgrading should solve this issue. 
FYI the current stable release of Evolution is 2.4.x
