Right, for detailed information see:

http://www.redhat.com/archives/rhl-devel-list/2007-November/msg00171.html

I don't understand how the /home/dhowells/rpmbuild/.. path triggers
this since it would appear to be considerably longer than 15
characters.  We would need to see the actual debugedit command line
(which I don't think rpmbuild prints).

BTW the source of the error is here:

http://rpm.org/gitweb?p=rpm.git;a=blob;f=tools/debugedit.c;h=0f85885e38a406f20f5b3779915908b4069691ea;hb=HEAD#l688
