Mail Crashes While Opening

Question

I posted a message in another topic similar to this one but I didn't notice it was for Tiger. Mail crashes while opening, I've tried to repair permissions , restart ect. I've also tried holding shift down while starting mail. Please Help!
BTW: I was asked if this is related to my other post "Oddness' well its not. I haven't had a kernel panic in 2-3 months I was just questioning what causes them.
It is Mac OSX 10.3.9

RAP,
In general, this looks OK, although the empty folder could be an irritant.
We could go a couple of ways: one would be to allow and force Mail to re-index this mailbox -- this would be done by deleting everything from the package EXCEPT the mbox file (which contains actual message contetn), and trying to launch Mail.
Another thing, and perhaps the next thing, is to remove the mail preferences, as mentioned earlier. To do this, first review all Mail Preference information to be sure you have it all documented and written down. Then quit Mail. In the Finder, open Home/Library and control-click on the Mail folder, and choose Duplicate -- drag the resulting copy to the Desktop strictly for temporary backup.
Next, open Home/Library/Preferences and locate the com.apple.mail.plist file, and drag it to the Desktop (likely to later delete). Launch Mail, and re-enter all your account set up info -- DECLINE any prompt to Import anything -- if the preferences are not empty at the launch of Mail, post back immediately. Once you have setup the account(s) again, and if it does not crash, then Mail should find everything already in the Mail folder, and this may resolve everything.
Ask any and all questions, and be comfortable that you know how to protect the messages saved -- that is what the copy dragged to the Desktop is about.
