I'm getting this all the time now so I guess it counts as a bug. Only on upgrading from 10.4 to 10.5

Every machine that I upgrade to 10.5.6, mail freezes up. It opens, upgrades mail database and then hangs and needs to be force quit.

The fix seems pretty straightforward, to bin the prefs file in the user library and reimport all the mail etc.

It's annoying though since you need to remember to make a note of all your mail settings before you upgrade.

Yes, and it is atrocious that Apple still hasn't fixed this yet. How long has Leopard been out now?

upgrading isn't a perfect art yet, hopefully snow leopard will make upgrading as efficient as it should be

A few obscure third party apps, yes that's excusable. A major part of the OS infrastructure and users day to day experience. Not. At version 10.5.6 this should not be a "feature of an oS upgrade.

Waiting for Snow Leopard and shrugging does not absolve Apple of responsibility for a major OS flaw.
