I could very well be wrong, but according to RMS anything using  
readline *is* infected:
http://clisp.cvs.sourceforge.net/*checkout*/clisp/clisp/doc/Why-CLISP-is-under-GPL

I would be interested in knowing why this is _not_ the case, i.e. what  
caused clisp to have problems but not IPython.

Not a big fan of the GPL,
