Chat error message: can't read "dlgstate(w)": no such variable

[v_2e]

  I have encountered the strange error messages and behaviour recently trying to chat with one of my jabber contacts. When this person sends me a chat message, I get an empty (though there is quite long chat history for this contact) chat window and an error message window with the following content:

Hook newChatMessageHook failed: 1
can't read "dlgstate(w)": no such variable
    while executing
"set w $dlgstate(w)"
    (procedure "::Chat::GotMsg" line 92)
    invoked from within
"::Chat::GotMsg {message {from <email address hidden>/laptop id ab1ba xml:lang ru-UA type chat to <email address hidden>/Coccinella"
    ("eval" body line 1)
    invoked from within
"eval $func $args"
can't read "dlgstate(w)": no such variable
    while executing

do you get the error every time you get a message from this contact?
do you use separate chat windows or tabbed chat windows?

No, sometimes I get the chat messages from this contact successfully.
I use tabbed chat window. Is it possible to use different chat windows for different conversations actually?

In preferences -> Appearance you can switch "Use tabbed interface" on and off.

I tried to reproduce the issue with both tabbed and non tabbed interface, but with both I was unable to get the error message. So due to your question I guess you use the tabbed interface.

Do you have any chat window open when you receive the error message when you get that error, or is coccinella opening a new window? When you have a chat window open, is there already a tab open for this contact, or is coccinella trying to open a new tab? In case there is a tab already, is it the active tab when you receive the error message?

It happened several times under different circumstances.
1. I had no chat windows opened. That person sent me a chat-message. I got an error message, pressed "OK" and heard an incomming chat-message sound. After that an *empty* chat window opened. No messages from history and no newly sent messages.
2. I had a chat window opened with one or two tabs. Then that same person sent me a chat message. I got an error message, pressed "OK", heard the incoming chat message sound and then a new tab for this new conversation appeared. It was empty.

I must note, that in any case, I can use this empty chat window to send the chat messages to my contact. And he gets those messages. But once this error occured, I cannot see any messages from that person until Coccinella restart. But it does not always work after a restart.

And by the way, I have a pretty long chat history with this contact (for a couple of years or so) and this is the first time such error occurs.

hrm, I love those bugs I cannot reproduce ;)

do you can move the chat history file out of the way, just to see whether this is the cause of the trouble then, and report back?

[buzzdee (sebastia)]

btw, which version are you using, I guess the latest release or a breakfast build?

[v_2e (v-2e)]

Yes, I can remove the history file for the experiment purity. But it works correctly right now, so I'll wait for the next error case and then report back if it happens.

I use Coccinella 0.96.21.
