I can reproduce the same (or a similar) error list on a debian linux
machine with fontconfig 2.4.1, too. It is easily reproducible by
creating a widget, destroying it (this is the important bit), and
creating another widget. The problem vanishes if the FiniFont call in
TkpDeleteFont in tkUnixXft.c is skipped. I also don't know yet if it's
a Perl/Tk or fontconfig problem, but it smells like a problem of the
latter.

Yes, determining when font-related tests should be skipped were wrong.
Due to my (default FreeBSD?) fontconfig configuration, I get the
original X11 font if helvetica was requested:

   $ fc-match helvetica
   helvR12-ISO8859-1.pcf.gz: "Helvetica" "Regular"

The skips will be correct in the next version of the patch, hopefully.
