R help - Dec 2006 - R[1821] *** -[NSBundle load]: Error loading code

I get the following error message every time I run R. I am on an  
Intel Mac, Mac OS X, 10.4.8:

2006-12-08 16:59:40.564 R[1821] *** -[NSBundle load]: Error loading  
code /Users/michael/Library/InputManagers/Smart Crash Reports/Smart  
Crash Reports.bundle/Contents/MacOS/Smart Crash Reports for bundle / 
Users/michael/Library/InputManagers/Smart Crash Reports/Smart Crash  
Reports.bundle, error code 2 (link edit error code 0, error number 0 ())

[Apologies if this has been answered before, I'm new to the list, and  
searched as well as I could...]

Thanks in advance for any advice.

Cheers,
Mike
