Mail crashes consistently

[lawyervon]

My Apple Mail crashes on startup. I start it up, it goes for a little bit, then crashes almost every single time. It's been doing this for weeks now, and I'm getting tired of it. Here's my Console entries from the Mail startup to the crash:

DayLite is an add-on that connects my emails to my DayLite Organizer database. Typically, I've had no problem with that. I'm not sure what this other stuff is.

Any help?

Just crashed again. Usually, after the 1st crash, it stays up the 2nd time. This time it crashed a 2nd time. More Console entries from the 2nd crash:

What did you change right before the problem started? Upgrade to Leopard, software update of Leopard, etc.? Having no extra information my first guess would be an incompatibility of the bundle with Leopard Mail or the 10.5.2 Mail. First thing I do when running into issues with software with addons is remove the addons and see if the problem persists, which is my suggestion to you. Uninstall the DayLite bundle, restart your machine and see if Mail regains its stability. My money is on it not crashing anymore.

That being said, I see in the crash reports that SyncServer is running, which should mean that you are using .Mac. There were issues in the April updates that caused SyncServer issues. Here is a forum post about issues people had and how they corrected it.
