Yesterday I wrote a long post venting about the issues that 10.5.6 has brought to me and to my Macbook Pro. I was having a problem with mail crashing every time I loaded a message with an attachment. Well, I am delighted to report that the issue has been fixed thanks to a user by the name of Til-Berlin on the Apple discussion forums:
In the end I found out that I have two Mail.app on my HDD. Apperently I was using a old updated (which reports also as 3.5). Deleting it and using only the one at /Programs solved my issue. I believe this is the application file from the Combo Update.

I looked at the version of Mail I was using from my Dock icon (Mail Menu > About Mail) and noticed that my version was 3.5 897.2/903.3. This is the problem. The current version of Mail is 3.5 903.3 only! I did a quick spotlight search on my mac to find 2 versions of Mail, one was the currupt one that I was using, and one was the good version (3.5 903.3.) I removed the bad one (3.5 897.2/903.3) and then added the good one to my dock, and opened it up. IT WORKED!
Til-Berlin suggested to reinstall the combo update after all of this, but I didn’t have to do this.
I hope this helps everyone who is having problems. You can check out my other post with fixes and details on the problem here: http://atlchris.com/582/os-x-1056-i-hate-you/
