The Wolfram Notebook Indexer for Spotlight is also a part of all of the versions 
you mention.  And version 8 includes the Wolfram Mathematica browser plugin,
which is installed as a part of the "Mathematica Extras" installation.  But
Mathematica doesn't actually use either one of these components while running 
(it might query their presence, but it doesn't use them).

Aside from that, your list of locations is a complete list (not accounting, of 
course, for document or data files you deliberately created in Mathematica).

A good place to begin when debugging SystemInformation[] is to try it a piece at 
a time and see which piece is causing the problem.  At the top-level, you could 
start with this...

Scan[(Print["Trying SystemInformation[\"", #, "\"]"]; Pause[2]; 
   SystemInformation[#]) &, {"Kernel", "FrontEnd", "Links", 
  "Parallel", "Devices", "Network"}]

You can then narrow down with a list of subproperties once you know the 
top-level selector which is causing problems.  If you need the list of 
subproperties, let me know which selector you needed it for and I'd be happy to 
provide the code to test the subproperties.

Obviously, a problem (you didn't say...a crash?  hang?) in SystemInformation[] 
can often be a bug in Mathematica.  Not so obvious, though, is that sometimes it 
is *not*.  For example, we've come across buggy video drivers or HID device
drivers which cause Mathematica to crash.  We try, of course, to work around the 
problems when we can, but it's not always possible.
