That bug has been opened on https://launchpad.net/distros/ubuntu/+source/evolution/+bug/37531 "This behaviour is still present in Evolution 2.6. (Dapper Drake) ... the selection changes, although it doesn't add/change the signature in the message. ..."
Can confirm this behavior.
This is fixed. :-)
confirmed fixed on GNOME 2.24
