I had this same problem with 9.04 too. After reading Dennis Cohn's quote, I upgraded to Karmic, and the problem went away until a few days ago. Thunderbird is now shutting down after an unspecified time. Trying to restart it results in Thunderbird appearing briefly (i.e. before email list displays) and then shuts down.
