... but findutils 4.2.28 was released in 2006.  If your point is that a
problem remains unfixed, you should be testing with a somewhat newer release,
surely.  

In any case, the "argument list too long" relates to a kernel limitation, not
a bug.  The -I (-i) option as specified by POSIX (see for example
http://www.opengroup.org/onlinepubs/009695399/utilities/xargs.html) requires
the whole input line to be substituted.  But the input line itself exceeds the
kernel's exec limit.
