Please re-read my previous comment. Unless you patch python there is 
nothing an application can do to prevent this. We _do_ handle 
KeyboardInterrupt exceptions by the way, just that most people don't get 
to see that one as it simply silently quits.

Title:
  Does not handle KeyboardInterrupt

Status in command-not-found handler:
  Won't Fix
Status in “command-not-found” package in Ubuntu:
  Invalid

Bug description:
  I get:

  
  File "/usr/lib/python2.7/site.py", line 562, in <module>
      main()
    File "/usr/lib/python2.7/site.py", line 545, in main
      known_paths = addsitepackages(known_paths)
    File "/usr/lib/python2.7/site.py", line 327, in addsitepackages
      addsitedir(sitedir, known_paths)
    File "/usr/lib/python2.7/site.py", line 195, in addsitedir
      addpackage(sitedir, name, known_paths)
    File "/usr/lib/python2.7/site.py", line 148, in addpackage
      f = open(fullname, "rU")
  KeyboardInterrupt

  
  Whenever I press ctrl+c to stop it from running, using 0.2.44.1ubuntu1. It shouldn't be erroring out when I wish to cancel it.
