yeah that crash is a shutdown hang. So I think the shutdown is not occurring so you get a crash when you attempt to revive it.

Perhaps check the task manager to see if Thunderbird is already running ( as a process, not necessarily as an application) before you attempt to start it and confirm.

I can confirm that no TB processes are running when I start TB. Still get the same 30-seconds-unresponsive behavior. Memory just keeps climbing. I shut down all processes and start it again and the same thing invariably happens. TB safe mode and Windows safe mode have no effect - still unresponsive after 30 seconds or so.

How many pop accounts? And how many imap accounts?

The problematic profile is a pop account.

I was able so switch to a different profile to get TB to work again. So is there a way for me to migrate data from the bad profile to the new one? Lots of messages in folders that I want to preserve.

Or is there a way for me to repair the bad profile?

Looking at some of your other crash reports in Help > Troubleshooting information, are they all @ shutdownhang | nsINode::ComputeIndexOf ??

jhanderson?

The notification system had been broken for several weeks, so I'm posting again to be sure you saw my response earlier.

If you still have trouble, please post more detail.
