If I'm for example in #gnu on freenode and have to disconnect from the server, the #gnu tab remains but I'm disconnected. If I think I don't need to go back to #gnu and close the tab while I'm disconnected, upon reconnection to freenode the tab is reopened, Konversation joins #gnu again. This is the situation as of git version "1.3.1+git457.g8b28316", and was the situation in current git master as of a few hours ago. But it's no longer the case with http://quickgit.kde.org/?p=konversation.git&a=commit&h=4e1e16a00d894df799c82175f46faf2b15a13972 Thanks to Eike Hein for confirming the issue and for the quick fix.
