If it has syntax, it isn't user friendly.

That's certainly odd.... I don't see anything in your .Rprofile which
raises red flags, but you can confirm by running

R --vanilla

which will ignore all environment settings, .*(rc|profile), saved sessions etc.

I presume you've tested in a fresh session and seen this behavior
consistently? If so, could you provide your sessionInfo() and source
of the binary you're using.
could my .Rprofile be at fault?

Use the usual debugging strategy:  simplify things.  Do you see the 
problem when you're running plain R, with no ESS?  Do you see the 
problem when you run R with the --vanilla option?  Do you have a script 
that reliably causes the failure?  Simplify it to a minimal script that 
causes the failure.

If you don't have a reproducible script yet to cause the error, then 
work on creating one.  (The next time you see it, save the entire 
history of the session, and see if re-running that history in a new 
session will reproduce the error.)
