Update: if you’re using OS X 10.7 Lion (not Mountain Lion!) and you have a similar problem, perhaps this information could help you.
My friend noticed that after he updated to Mac OS X Mountain Lion some applications (including famous TextWrangler and various application installers) started to crash every time right after being launched. (It later turned out that for other users the same problem also affected Google Chrome, Evernote and iPhoto).
I noticed that the crash logs of those applications contained the same errors.
Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE ...

and in Console I found the following errors:
Job appears to have crashed: ... Abort trap: 10
Data/Stack execution not permitted ... protections were read-write
After digging Google I came across a very helpful thread in the Chromium project issue tracker with the solution:
1) Run in Terminal:
sudo update_dyld_shared_cache -force
