982823 - Conversation pane blank after today's trunk update

Status: RESOLVED DUPLICATE of bug 982820

(Thunderbird :: Instant Messaging, defect)

Description

[Joe Sabash [:JoeS1]]

Completely blank pane, but clicking on Previous Conversations>>Today shows activity.
Selecting 'Back to current conversation' returns to blank pane.

Not sure exactly when this error occurs:

I haven't seen before the error message you pasted here, but there's a regression in today's nightly that causes the conversation pane to be blank. We are fixing it in bug 982820; so hopefully the next nightly will be more usable.
