I can confirm that this bug can happen with no existing conversation windows present. Also reporting odd behavior of conversation window, which may provide some insight into the crash. Here's the sequence as best I can remember:
* no conversations present
* have gone idle
* beep (incoming)
* window appears in upper left of screen (call it "top")
* several incoming messages into "top"
* I start typing into "top"
* more incoming messages into "top"
* somewhere in here, "top"
* a new window appears in lower left (call it "bottom"), containing the conversation that "top" contained
* I can send and receive and start new conversations in "bottom", but gaim will crash if I touch "top".
I think that gaim is opening the new conversation twice, and then some ambiguity over the appropriate window is causing the crash.
