--- Comment #3 from Fabio ---
I debugged this issue a bit.
There's a workaround, just disabling "Input auto-resize" from the "Format" menu
avoids the crash when closing the chat window.
The crash is due to KopeteRichTextWidget triggering a size recalc on the
chatview of the window that has just been closed; this leads to a call to
ChatMessagePart::keepScrolledDown() to ensure the view is scrolled down to the
last message. Here's the backtrace up to the method emitting the signal:
