           Summary: a channel can be open in two tabs at once after /msg
                    #channel
           Product: konversation
           Version: 1.0.1
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konversation-devel kde org
        ReportedBy: ais523 bham ac uk


Version:           1.0.1 (using 3.5.9, Kubuntu (hardy) 4:3.5.9-0ubuntu7.1)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.24-17-generic

I was in the channel #irp on irc.freenode.net (although this bug seems not to depend on the channel, I've reproduced it in #esoteric on that network too), and typed the following command (without the quotes) into the text box where messages are typed and pressed Enter: "/msg #irp " (note the trailing space at the end). I expected this to send a null message to that channel. Instead, it caused a new tab to open, also apparently to the channel #irp (it had a log extract at the top, as if I had just joined a query). I repeated this in #esoteric (which was more active), with "/msg #esoteric ", and tried sending messages from both the original #esoteric tab and the new tab that had opened; messages from either tab reached the channel, and all messages from that channel appeared in the original tab.

Further experiment shows that this bug seems to reproduce every time, and that the whitespace at the end is irrelevant (the same effects happen whether there are no spaces or two spaces at the end). Closing the second tab does not cause me to part the channel. I haven't tried closing the original tab in such a test yet.

This is a user interface bug; the current behaviour is counter-intuitive, as having a channel open in two tabs at once makes no sense. I'd expect to either send a blank message, or to get no response from Konversation at all, or possibly an error.
