Why do my applications keep crashing on Lion 10.7.3? Once every couple of days an application crashes on my MacBook Pro with Lion (10.7.3).  It's also running the newer build that's supposed to have fixed these issues (11D50b).

This has been happening to me ever since I upgraded to Lion.  I brought the MacBook Pro to the Apple store and the Genius did some tests and said there are no hardware issues.  I even did a full clean OS reinstall hoping it would make the problem go away, but it still occurs.

Here's the latest example (below), I just clicked the red "close" bubble in the TextEdit title bar and this happened.  But it can be any application that crashes.  It seems random.

I've also tried creating a new account to test whether it's something unique to my profile but apps crash there too. 

Why does Lion keep crashing apps on me?

Yep, your problem sounds just like what a ton of others were having. Re-update using the combo update from the Apple Web site, and that should cure what ails you. Do Not redo your update using your Apple's built-in Software Update.
