How do I recover from Crash on Start?

***First off, I believe that I have bad RAM, because this machine will seg fault out of the blue. However, periodic "memtest"s (and the Apple Store geniuses) indicate nothing wrong with the hardware. Apple refused to replace it, stating that it was a bad Java version, because all my core dumps were running Java apps when they crashed. That doesn't explain the Ruby, Python or C code that can seg fault for no reason either... 

Sadly, Sublime Text 2 crashed today. (http://pastebin.com/Nn01swWN) 

Even sadder, I cannot get past this system alert popup; it keeps crashing on launch.

Unable to run package setup:

What can I do to use this app? Just reinstall it? I tried to remove the "Data" folder, but all I see are Backup, Installed Packages, Pristine Packages, Settings. 

>>> Okay, before submitting this question, I pulled all installed packages out of ~/Library/Application\ Support/Sublime\ Text\ 2/Installed\ Packages and onto ~/Desktop. Then relaunched the program. It complained about missing some extension. So I dragged them back. It works! 

Until I close it... 

When I relaunch, I get the exact same popup. And it closes when I click "Ok."
