Hi Peter:

The offending call is in ensure_send_progress_dialog, passing "parent" as the 
transient parent for the send-progress dialog, which is in turn called from 
lbs_process_queue_real, passing SendQueueInfo::parent. Gdb shows that send_info->parent 
is not balsa_app.main_window, which is supposed to be passed down from 
send_queued_mail_activated. It's also not been NULL, in the cases I've looked at.

Oops--I was looking at the wrong code path: if it's an instant send, not a 
queue-and-send-queued, the parent is the compose window, and it sometimes gets 
destroyed during the async check for reachability. Adding a ref/unref should 
keep it alive long enough.

Hmmm, I wonder if this would really be the reasonable way...

I think the user expects that the message is either sent or queued /somehow/ whenever 
[s]he hits the send button.  Remember that the "real" send process may be 
delayed for some time, e.g. if a dial-up connection needs to be established (maybe ~30 
seconds in this case).  Still showing the composer sounds impractical to me.

This means that the composer dialogue should be closed, regardless of the state 
of the send process.  Which in turn implies that the usual state would actually 
be the destroyed parent!

You're right, of course--not much point in using the async method if the 
compose window is held open until it finishes!

IMO, there are two proper ways to deal with this situation:
1) always use the main window as parent, when showing the send progress dialogue
2) use that status bar in the main window to show the send progress

However, #2 might conflict with a pop3 download progress...

What do you think?

1) looks good to me. I was actually surprised to see the compose window code 
using the compose window as parent.

Best,

Peter
