Yeah, sure.  Sorry I didn't do this - I only know "run", "stop" and "bt"
commands in gdb...  :-)

This trace starts from when I press the get mail button:

sending queue
sending : A00077 LIST "" "mail"
received: * LIST (\NoSelect) "/" mail
received: A00077 OK LIST completed
sending : A00078 LIST "" "mail/Mailing Lists/Galeon"

  [ ... ]

reading a few mails, sending a mail then pressing the get mail button.
