Comment (by pulkomandy):
More precisely, it seems there is an infinite recursion of this sequence:
{{{
959 0x7056be40 0x19b5596
BPrivate::BContainerWindow::MessageReceived(BMessage*) + 0x1ba
960 0x7056bf90 0x19f4d0b
BPrivate::TFilePanel::MessageReceived(BMessage*) + 0xa67

972 0x7056cc00 0x19b5596
BPrivate::BContainerWindow::MessageReceived(BMessage*) + 0x1ba
}}}
It looks like:
* Message is dispatched to a BTextView (971)
* The BTextView does not handle it, so it propagates up to BHandler (965)
* BHandler tries to propagate the message to the next handler (964)
[https://www.haiku-os.org/legacy-
docs/bebook/TheApplicationKit_Messaging.html#TheApplicationKit_Messaging_Inheritance]
* After a few hops through the handler chain, we end up in
BPrivate::TFilePanel::MessageReceived and the message is dispatched to the
window again, restarting the cycle.
